Different ways to measure noise at work

Do you have any day job? Do you work in a noisy ambiance? If so, you might want to assess the noise level in your workplace. As a thumb rule, if you have to yell to your colleague that is just 6 feet away from you, know that the noise level is very high. If we put it differently, the noise level should not be higher than 85 decibels and you should ensure db noise level measurement through the following ways:

Sound level meter

You may buy a sound level meter from the market. With the assistance of this meter, you will be able to assess the noise level within a few seconds. You may also utilize an Android app for the same purpose. You can also control noise by using a soundproof sliding glass door.

Field calibration

For the majority of occupational and environmental noise level monitoring legislation, one necessity is filed calibration. Noise measurement equipment like a sound level meter should be calibrated before and after every use. You may also use soundproof accordion doors.

Good Trend

It is a great idea to ask question to your workers to know working activities and practices along with the activity durations. Other than this, you might want to take notes to the working position of every worker.

Excessive noise

Remember that prolonged exposure to noise might cause permanent damage in hearing. Hence, it is vital to understand that the level of damage is based on the noise level and also the time period you were exposed to the noise.

Hence, if you have been looking for a way to assess the noise level in your workplace, we recommend that you contact a good expert. Possibly, you will be able to ascertain and control the noise level by using a soundproof window panel.

Ongoing residential noise problems=

Ongoing excessive noise issues can be difficult to prevent.

Residential noise complaints - such as those involving people, parties and music - need to be lodged as and when noise occurs. Action can only be taken when the noise is happening.

We use the Resource Management Act 1991 Section 16 to enforce excessive noise, which requires an officer to assess the noise before taking action.

If the noise is assessed as excessive, the Act allows the noise control officer to issue an Excessive Noise Direction (END) notice, which requires excessive noise to stop for up to 72 hours.

Further excessive noise within the 72 hours can be subject to enforcement action, including a $500 fine or seizure of the noise making equipment with police assistance.

After the 72 hours has elapsed, a new noise complaint will need to be made and, if found excessive again, a new END notice needs to be served.

Further incidences of excessive noise need to be reported as they occur and be re-assessed. In each instance, you need to call us on 09 301 0101 so an officer can be dispatched to assess the noise.

If you have made complaints and the noise is still audible=

If you have made complaints and the noise is still audible

If they are approachable, try talking to your neighbour. Often noise issues can be solved with a friendly chat.

If it is a tenanted property, talk to the landlord or property manager. Under the Residential Tenancies Act, a landlord can issue a 14-day notice for tenants that cause disturbance to the neighbourhood.

If the noise originates from the back of a property, down a driveway, or somewhere where the noise is screened or reflected, our noise control officer may not have heard it from the road. We need an accurate description of the noise source.

Ongoing industrial, commercial or mechanical noise problems=

Unreasonable noise from industrial, commercial or mechanical sources are generally at a lower decibel level, but more continual than residential party or music noise.

Examples include:

a loud bar or nightclub

construction noise

a factory or industrial noise

heat pumps, pool pumps or ventilation fans.

Calibrated sound level meters are used to measure such noises. If found to be unreasonable, the person responsible will be asked to correct the situation. If not remedied, abatement notices can be served and enforcement action taken. This includes infringement fines or possible prosecution.

We assess it under the rules of the Auckland Unitary Plan.

In order to best assess the noise, multiple visits may be needed to correctly measure it. Depending on the nature of the noise, a control officer may need to make an appointment to measure the noise from your property.

Decibel Meter

A decibel (or dB) measures ratios of power or intensity. It expresses them as an exponential function. One bel is a power ratio of 10:1, and is divided into ten decibels. An increase of three decibels is approximately a doubling of power. Decibels are often used in measuring telecommunication signals.

MEASUREMENT

An abundance decibel-reading apps for smartphones make it easy to learn how much noise is in the world around us. Most apps use the smartphone’s microphone to give a reading of the decibel level.

As with a professional-grade meter, most phone apps can also show how the noise fluctuates over time, in real time, and provide numerical reference points that users can compare to their own sound levels. Some apps even let you geo-tag the decibel level to a specific location, like your favorite restaurant or your workplace.

HHF used Decibel Meter Pro to record the noise levels of hundreds of New York City subways. The samples show the average noise levels on all subway platforms and on all subway rides (inside subway trains) is between 72.5 and 76.5 dB and between 74.1 and 75.8 dB, respectively. With maximum readings actually as high as 119 dB on platforms and 120 dB on rides—based on actual recorded data within the sample—the subway system is an auditory minefield.

Rotating speakers on Vizio's Elevate soundbar aren't just a gimmick

Rotating speakers on Vizio's Elevate soundbar aren't just a gimmick

Ty Pendlebury/CNET

Soundbars capable of reproducing the atmospheric effects of Dolby Atmos soundtracks have been around since 2016, but until now they haven’t been very innovative. To work well, Atmos devices need extra speakers to reproduce those height effects, and usually they’re small, static drivers aimed at the ceiling. The Vizio Elevate costs a bundle but it tries something radically new: motorized speakers that rise up and revolve according to whether you’re listening to music or a compatible movie. The craziest part is, it actually works!

Like

Motorized speakers work well.

Excellent sound for movies and music.

Plenty of connections

Includes rears and wireless sub.

Don’t Like

Not as easy to use as Sonos Arc

No Apple AirPlay support

Somewhat short surround cables

The Vizio Elevate is expensive for a soundbar, but Atmos bars in general have always tended toward the high end. The Samsung HW-Q950T comes close in terms of specification but that system is also $1,700. The Sonos Arc ($799 at Sonos, Inc.) offers the simplicity of a single bar and includes a voice assistant, but it doesn’t sound as good as the Vizio. With its moving speakers, the Vizio Elevate really is its own animal.

Newbies beware however: The Vizio Elevate’s manual setup can be complicated and isn’t helped by the confusing remote. Some users may also find the wired surround speakers a pain depending on where they choose to place the subwoofer — the cables are probably too short for large rooms.

The rotating speakers reek of gimmickry, but in practice they work well, adding oomph to music and spaciousness to true Atmos soundtracks. If you don’t mind plunking down the money for a fully featured, great-sounding soundbar, the Vizio Elevate is a very serious contender. If the Elevate is too rich for your blood, however, the Vizio SB36512 is our Editors’ Choice winner and an excellent alternative at less than half the price.

Build quality: A step above

Ty Pendlebury/CNET

The Vizio Elevate is a 5.1.4 soundbar which offers compatibility with both immersive standards: Dolby Atmos and DTS:X. In addition to the main speaker itself, the Elevate’s setup includes rears, a large subwoofer and a remote. If you wanted to deck out the Arc with a similar array of speakers, namely the Sonos Sub and two Symfonisk for the rear channels, it would cost about $1,700.

The Vizio Elevate may be a plastic soundbar at heart but its design is… ahem… elevated. The main bar feels sturdy and comes in a two-tone finish — part thick vinyl wrap and part gun-metal aluminum. This is a big speaker at 48 inches wide and a table-swallowing 6.5 inches deep. The ends are covered in a matte-black material, which makes it hard to see the matte-black controls, but the raised buttons are actually easier to use by touch. The front of the soundbar includes a colored LED that makes it relatively simple to tell which input you are on, as well as a white LED level meter.

The main speaker features a whopping 13 drivers, including a dedicated center channel and 5 tweeters in total. The swiveling speakers are situated at each end and rotate when the system detects a Dolby Atmos/DTS:X signal, revealing the Atmos logo on one side and DTS:X on the other. 

Ty Pendlebury/CNET

The subwoofer is one of the largest I’ve seen on any system, measuring 11 inches wide by 14 inches deep and 16 inches high. The rear speakers feature both forward-facing and upward-firing drivers and are tethered to the sub by a 30-foot cable (the connection between the soundbar and the sub is wireless). The cable was long enough to drape behind my couch and along the side of the living space to the sub at the front, but the length could be an issue for some installations. 

Vizio claims the system is capable of 107 decibels, and I did find it was quite loud, so no worries about filling even the largest living spaces. The Elevate includes a wall-mount bracket in the box (BYO screws, however), and Vizio designed the bar to mate seamlessly with the Vizio OLED TV.

A mountain of features

Connectivity is excellent with two separate HDMI inputs, as well as a third, labeled “HDMI Out,” which supports eARC. There’s also an optical digital input, a 3.5mm analog audio and a 3.5mm “voice assistant” input, USB and Bluetooth. The Elevate connects to your network via Wi-Fi and supports Spotify Connect and Chromecast built-in. Unlike the Arc, it lacks Apple AirPlay support but its physical connectivity is far better than the Arc’s.

Ty Pendlebury/CNET

The Elevate also lacks a built-in voice assistant, found on the Arc and other soundbars, but I don’t see this as a major disadvantage. Using Alexa or Google Assistant on a soundbar can be annoying as the volume will mute if it hears the wake word, which means you could miss some of your show. If you want to use a voice assistant to listen to music through the Elevate it’s easy to set the soundbar up as the default speaker for an inexpensive Google or Echo speaker nearby.

Ty Pendlebury/CNET

The remote looks like the ones that come with cheaper Vizio soundbars but differs in two important aspects. There’s an LCD display at the top, and four buttons which help with setup at the bottom. Having both Effect and EQ options is a little confusing because they perform very similar tasks, and navigating menus via the different buttons takes a little getting used to.

Adjusting the volume of the subwoofer was easy enough with the Level button but not everything was intuitive, and you will need to know to download the Vizio SmartCast app to complete the setup of Wi-Fi, for example. I also had some issues updating the firmware from the website, but Vizio told me it was because one of the files was misnamed and assured me it was now fixed.

In comparison the Sonos Arc was a simple pleasure to use, install and update, although that speaker’s setup does heavily favor iPhone ($599 at Apple) users — Sonos’ TruPlay calibration app is not available on Android. I had some issues with the Arc initially and these were helped by using TruPlay (on an iPad ($385 at eBay)).

High and mighty sound

The Elevate is twice the price of the existing SB36512, but you can’t expect twice the performance. I was unable to test the two models side-by-side, but in my experience there are always diminishing returns when going from an excellent, affordable speaker to a much more expensive one. 

For these tests I compared the Elevate side-by-side against the Sonos Arc, because the two are roughly the same price. The Vizio acquitted itself very quickly with authoritative sound quality across all kinds of material. Unlike the Arc, which performs better at home theater than music, the Elevate was equally capable with both — a rare feat among soundbars.

I started my tests with music, Radiohead’s My Iron Lung to be precise, and I found that the Arc wasn’t quite as accomplished as the Vizio. The Arc played the song at a remove, slightly boxy and distant. By fiddling with the EQ I was able to improve definition to the percussion, but Thom York still gave the impression he was phoning it in. The Vizio was the opposite, lively and punchy thanks to that subwoofer. It wasn’t quite perfect, though, as I needed to back off the treble a little, but much more listenable overall.

I moved to something more ethereal with Yulunga (Spirit Dance) by Dead Can Dance, and the Arc improved somewhat, with a crispness and presence in the stereo shaker eggs for example, even if it wasn’t able to dig deep on the larger drums. The Vizio’s authority was evident from the first few bars of the song. Lisa Gerrard’s voice floated free of the speakers, and the string accompaniment was easier to hear. The sub was able to let the drums and gong sounds fully resonate in my testing room.

I moved to movies and TV next, starting with the infamous egg-stealing Chapter 10 of The Mandalorian. The episode features a chase scene through clouds and an inevitable canyon run (it wouldn’t be Star Wars if you couldn’t flip your ship vertically or had to contend with guard rails on gang planks). During this scene the Arc was able to convey a real sense of height as the Razor Crest descended into the frosty planet’s atmosphere, pursued by two X-wing fighters.

As lovely as the Arc sounded, it was the Vizio’s dedicated rears and sub which really helped anchor the action. The Elevate’s surround effects were much more pinpoint and the metallic thud of the ship as it skidded across the floor of the icy canyon sounded impactful and scary. It didn’t have the same vertiginous feeling of height as the Arc however.

The sub and rears again helped the Vizio convey a sense of space in my next test, the Thanator chase scene from Avatar. Insects buzzed around the listening position, dialogue was clear and explosions bombastic. In comparison with the Arc, it could occasionally send an insect-like click to my right that made me think the Elevate’s rears were somehow still working, but the sense of surround was much less palpable.

The revolution starts here

Are revolving, motorized speakers going to become a trend? Probably not. The up-firing speakers of the Vizio Elevate add some impact when in stereo mode it’s not really enough to justify a potential moving-part weak point down the road. 

The Elevate may not be as easy to use as the Arc, but it’s the better performer, and that’s really what matters. The Vizio soundbar is also a better value, due to its enhanced connectivity and dedicated subs and rears. The Vizio SB36512 still offers the best value of any Atmos soundbar I’ve tested, but if you want an upgrade, the nifty Elevate is a more refined and home-theater-ready speaker.

How Fiber Optic Light Source Works for Optical Communication Systems

For high capacity, digital transmission systems, and high-speed local area network optical fiber is the medium of choice. Besides these applications, to transmit microwave signals for cable television, cellular radio, WLAN, and microwave antenna remoting optical fibers can be used. The fiber interferometer is very useful.

 Some basic principles must be kept in mind all the time while testing loss in a fiber optic link.

Like the working wavelength, the testing wavelength should always be the same. Because with light wavelength optical fiber loss varies and if your measuring wavelength is different from the actual working wavelength you will get an incorrect result. 

As the intended working lightwave equipment light source the testing light source should be the same. If a particular system is designed for a LED source, you should test it with a LED source. You should use a multimode laser light source for testing if the system is designed for multimode laser light. For a single-mode laser light source, this is quite true. You can use the visual fault locator.

Four types of test equipment are needed in a basic loss testing setup. They are the reference patch cables, a light source, the power meter, and the adapter.

While choosing your equipment below are some considerations provided.

As the operating equipment, the light source should have the same wavelength, proper mode, type, and proper connector.

The power meter should also have the same wavelength as the light source, proper connector, and calibrated. You can buy the fiber identifier online.

The reference patch cables should be high quality with no loss, proper connectors, and be the same type as the fiber plant being tested.

The adapter should be made with high-quality ceramic sleeves and be proper type. Decibel is the most often used for fiber optic loss testing unit since it is much easier to work with.

What Is An IoT Beacon Innovation

IoT beacon innovation literally means radio beacon and also suggests a radio beacon, comparable to the light of a lighthouse. In the IT environment, beacons are utilized in numerous areas. Beacons can be little Bluetooth transmitters, status messages in a WLAN, or tracking pixel in a message or on a website, as well as much more.

The English term beacon suggests radio beacon in German. In the original feeling, it is a mobile or fixed radio station that is used in navigation, for instance in aeronautics or shipping. The radio beacon discharges radio waves that can be utilized to determine settings.

Apple's iBeacon and various other solutions A well-known execution of the Bluetooth beacon is Apple's iBeacon. It is a manufacturer-specific method based upon Bluetooth Low Energy introduced in 2013. From the iphone 7 os, Apple devices such as the iPhone or the iPad support iBeacon.

iBeacons typically do not send out press notices to obtaining devices. They do not accumulate or conserve data but send out info about their own identity or condition. Thanks to the use of Bluetooth Low Power (BLE), the devices function incredibly energy-saving. iBeacon modules attain series of approximately 30 meters and also are utilized, as an example, in smartwatches or video gaming pads.

Another IoT beacon modern technology implementation is Eddystone from Google. Eddystone sustains both Android as well as iOS tools. Radius Networks uses an alternative open criterion called AltBeacons.

The internet beacon is a monitoring pixel for sites or emails IoT sign modern technology is additionally used outside of wireless radio innovations. The web beacon is an alternate term for a monitoring pixel. It is a little unnoticeable graphic on an internet site or in an e-mail.

The web sign is typically just the minimum size of 1 x 1 pixel. With the help of these pixels, it is feasible to examine whether an e-mail was opened or an internet site was accessed. As soon as the tracking pixel is called up and loaded from a web server, a service registers this occasion. It is not apparent to the individual himself that the pixel has been asked for. The process is invisible to him in the background. Nevertheless, the driver of the web server can see exactly how commonly and also how many individuals request a particular internet sign. The following features can be executed utilizing web sign:

- Creation of a movement profile of a site visitor on a website - Figuring out the os, the browser version as well as other homes of completion device of an internet site visitor or email recipient - Identify the IP address of a site visitor or e-mail recipient - Figure out the approximate location of the internet site visitor or e-mail recipient through his IP address - Figure out the opening price as well as time of opening of email

The function of an IoT beacon technology in WLAN In a WLAN, a router or an access point sends a small data package called Sign at routine intervals. This bundle is a sort of status message that contains info regarding the network name (Service Set Identifier; SSID), possible transmission rates, and also the kind of security used. The Sign enables clients to quickly establish a connection with the WLAN accessibility factor. You only require some added information such as the password. The reception quality of a WLAN can additionally be monitored making use of the sign.

Yet signs can additionally have various other functions. In the IT environment, signs are also frequently made use of in various areas. It can be brief, regularly sent information packages in a WLAN, little, Bluetooth-based transmitters, or tracking pixels in a message or on a web site and much more. Apple has actually likewise created an exclusive technology called iBeacon.

Some settlement solutions utilize beacons to implement automated repayments without touching the sales register. IoT beacon modern technology plays an essential function in the Web of Things (IoT). With the help of radio modern technology, networked objects can trade information with each other. Beacons have great prospective, specifically in the location of commercial production as well as Industry 4.0. The technology can be utilized to recognize workpieces, machines, or individuals and also wisely network production procedures. Mobile applications and also tablets or smartphones can be made use of to control and also check the procedures.

How do you set up signs and exactly how do you ideal install them? There are currently four sign criteria: iBeacon from Apple, Google's Eddystone, UriBeacon, and Altbeacon. iBeacons still comprise the lion's share, yet Eddystone is steadily getting market share because of its intriguing homes. In today's blog site write-up, we handle the question of what settings can be affected by iBeacons as well as exactly how best to attach beacons as a whole to the place.

Report on the circulation of sign procedures

1. SECURING The signals from signs can be shielded by different materials. These can be wooden, concrete, or steel wall surfaces, for example. This must also be taken into account when setting up on columns in the room. The most effective place for signs is around 2.5 to 4 meters in height. At a reduced elevation, individuals can secure the signals. Positive areas are on walls in the structure and on beam of lights on the ceiling. A great alternative can additionally be mounted in light holders, as these are evenly distributed throughout the structure and also can provide the beacon with power. It is very important that there are as far as feasible no interfering things between the transmitters.

2. INTERFERENCES We are frequently asked by clients whether signs create disturbance in radio networks or technological gadgets as well as whether, on the other hand, sign signals can be falsified by them. We can offer the all-clear for the first case. Signs do not affect other signals and medical tools also stay uninterrupted. Nevertheless, if signs are mounted in a space with a large number of WiFi signals (for example at a profession fair), interference can occur since BLE and also Wi-fi share the same frequency variety (2.4 GHz).

3. SETUP OF IBEACON iBeacons lug a number of vital numbers as well as have several arrangement choices. This information can be seen and also modified utilizing a mobile phone app or software from the manufacturer.

UUID: the UUID normally sends the beacon's membership to a top group (e.g. "belongs to airport XY"). All beacons from this driver have the same UUID as well as can hence be appointed.

Major: This suggests which team numerous signs come from. For example, this could be all signs in Terminal 1 at Frankfurt Airport terminal. The objective of use can additionally be distinguished, for instance, "position decision automobiles" and also "navigation for vendors" in an auto dealer.

Minor: Recognizes private signs whose specific placement is taped on an electronic map.

TX Power is the signal strength measured in a calibration procedure one meter from the beacon (RSSI value-- got signal strength indicator). It is established as well as entered completely. The established transmission power can influence the accuracy of the setting resolution. Higher signal stamina means greater energy usage. TX Power is measured in dBm. Decibels milliwatt (dBm) is the power level in decibels based upon 1mW. High transmission power is for instance -59 dBm, whereas -81 dBm is instead reduced.

Transmission interval: The transmission period defines the time intervals (e.g. 1000 nanoseconds) the sign sends out signals. The same uses right here: the higher the transmission period, the greater the energy intake (double transmission frequency approx. Dual energy consumption). But it additionally suggests that the position can be identified quicker and also much more current.

Just how can you make use of iBeacons as well as IoT beacon modern technology in your home? An iPhone that thinks for itself: As soon as you take a seat at your desk, the Safari browser opens up; when you open up the refrigerator in the kitchen, the listing of acquisitions appears that is still to be done today and also in the evening when you are comfortable Sofa collections, the remote application for running Apple TV begins immediately.

This is possible with so-called iBeacons. The word "iBeacons" is an Apple production and was first pointed out at WWDC in June 2013. Generally, it suggests tiny hardware buttons that sustain Bluetooth LE (Bluetooth 4.0). These beacons send out info to the mobile device using Bluetooth. However, these beacons do not work alone, they require an ideal application that supports iBeacon innovation and IoT sign modern technology. MOKOSmart showed it a few weeks ago: For those who had actually downloaded the MOKOBeacon application, information as well as details about jobs as well as occupations appeared consistently on the apple iphone screen as quickly as the individual went to the relevant hotspots in the exhibition halls.

iBeacons versus NFC It works similarly with NFC. This modern technology was made use of at the Mobile World Congress. iOS devices, however, do not sustain NFC and also it doesn't appear like Apple will alter anything anytime quickly. Those who go to innovation fairs regularly can barely refute it: accessory producers are significantly depending on Bluetooth 4.0, while NFC is falling behind. NFC has the edge in mobile payments. But unlike NFC, iBeacons are able to offer a total room with its very own "network". When the customer gets in a shop, their mobile phone application informs them concerning current special deals. An additional benefit is that iBeacons take in very little electrical energy. If you believe some manufacturers, the battery needs to last approximately 2 years.

iBeacons for in the house In December 2013, Apple equipped 254 Apple shops in the U.S.A. with iBeacons, however in Germany that is still a long way off. There are currently some providers who sell iBeacons and also with Placed there is likewise an app with which you can also make use of iBeacons in the house. The prerequisite is that your iOS tools sustain Bluetooth 4.0. This is only the instance from the apple iphone 4S. The iPad 4, iPad Air, as well as iPad Mini with and also without retina present assistance this requirement for tablets. You should also enable the relevant applications to accessibility place solutions.

If you now put an appropriate iBeacon on the couch, fridge, or desk, particular activities will be activated as soon as you are within a span of one meter from the relevant item. Placed sustains apps such as MOKO Tag Beacon, Remote, the Timer, Wunderlist (to-do lists as well as task application), Safari, as well as the Sensational schedule app. After you have attached the iBeacon to the furniture piece, established its UUID or put the UUID that you obtained from the iBeacon maker. After that you define the applications or Links that should be active at this iBeacon. For example, the remote application for Apple TELEVISION begins automatically when you go to the iBeacon that is affixed to your couch.

You can likewise develop your own apps that work with the corresponding iBeacon. MOKOSmart gives IoT beacon technology and sign SDK.

Forward Onto A New Methodology

The intent of our CPU cooler testing methodology is to recreate real world yet repeatable testing conditions in order to comparatively benchmark competing heatsinks, AIOs and other cooling devices. We have decided to move well beyond the “slap a heatsink on a test bench and log results”.

  Testing Environment

Whereas we previously tested on an open, horizontally oriented test bench which relied on ambient air temperatures to create a stable testing environment, we have decided to move towards a different approach. After consulting with a mechanical engineer* who specializes in heat transfer as well as several OEM heatsink manufacturers we have validated the open system with the motherboard in a horizontal position can create artificially inflated results in certain situations.

This is due to the following factors:

The cooler placed vertically can allow it to wick away heat from the processor in a more efficient manner versus it being placed in a more natural horizontal position like you would find in a typical ATX case. It can also obfuscate the negative heat transfer effect brought upon by poor heatsink base finishing or an improperly designed mounting system. This can improve the results of products that would normally underperform.

Certain heatsink designs create localized heat zones around key motherboard components or run contrary to a enclosure’s typical airflow patterns. An open test system would not allow us to calculate the negative effect this has on key items such as inner case & VRM temperatures.

AIO’s can aid in case airflow in many situations (though not in a configuration where its pulling air into a case) by providing additional outwards-bound air movement and by exhausting much of the CPU’s heat immediately outside the case. This is one of their main benefits since it can drastically lower case temperatures but installing it in an open system will completely and unrealistically negate this benefit.

While testing on an open bench will still yield apples to apples results, they are not the ones we are looking for here. Rather, we wanted ours to represent more of a real world scenario, though under very tightly controlled testing conditions to remove sample variance.

With this in mind, we have decided to use a completely closed test system in the following format:

– Fractal Design Meshify S (tempered glass side window) – 2x Intake 140mm fans operating at a constant 600RPM – 1x Exhaust 140mm fan operating at a constant 600RPM – If an AIO is installed, it is placed on the top radiator bracket, exhausting air outside the case

  Other Test System Components

CPU: Intel Core i9-10980XE –  Stock Speed = ASUS Optimized Defaults (~150W – 165W) –  Overclock = 4.5GHz all core rate, constant @ 1.25V (~210W – 225W) –  Threshold for thermal throttling modified to 110°C

This may not be a common CPU but it allows us to test a wide range of thermal output conditions from 150W to approximately 225W (consumed power, not CPU thermals). If a cooler passes these tests, you can safely assume it will be more than adequate for more efficient processors from AMD and Intel.

Thermal Compound: Arctic MX-4 Motherboard: ASUS X299 Edition 30 GPU: ASUS RTX 2080 Ti STRIX OC Memory: G.Skill Trident Z @ 3200MHz Storage: Samsung 860 EVO 1TB NVMe SSD PSU: be quiet! Dark Power Pro 11 750W

  Interior & Exterior Environmental Conditions

Room Temperatures In order to maintain consistent temperature conditions, all testing is done within a room equipped with a dedicated HVAC unit and the capability to maintain ambient temperatures with a variance +/- 0.5°C.

With that said, ambient temperature is maintained at 22°C throughout testing and if it dips below or goes above that point by more than 1°C, testing is halted until things stabilize. This is monitored by a calibrated Extech Thermometer equipped with dual Type K thermocouples and an alarm set to notify if temperatures move outside our deltas.

Case Temperatures Before testing begins, the system is left at idle until interior case temperatures reach 25°C as monitored by a Type-K thermocouple placed ~1.5” away from the middle of the case’s upper radiator bracket.

Unlike exterior temperatures, interior temperatures are allowed to rise throughout the test. However, after each test is complete and before beginning the next one, the system is left in an idle state to naturally come back to 25°C.

A Note About Mounting Due to a number of factors, results can be highly variable from one cooler mount to the next. This could be due to a poor mounting method, insufficient / excess thermal compound, etc. In order to partially remove this variance, the results you see are the best achieved between two separate mounts of each cooler.

In addition, in order to normalize testing Arctic MX-4 thermal compound is used all comparative testing. However, all coolers are initially tested with their packaged TIM. If there is a large difference in results, we will report the variance within the review.

  Load Conditions & Logging

The load placed upon the i9-10980XE is through AIDA64 Engineer Edition System Stability Test (CPU test only). While logging is done through HWInfo64.

This is done for a constant 30 minutes are logs are pulled from HWInfo after this time has expired. The 30 minute load has been chosen since within this timeframe most coolers / AIOs reach their peak thermal saturation point or liquid temperature.

The following conditions are logged (only some reported): – Max CPU package temperature – Stabilized CPU package temperature after 30 minutes (logged & reported) – Max individual CPU core temperature – Max VRM temperature – Stabilized VRM temperature after 30 minutes – Interior case temperature after 30 minutes (logged in Extech thermometer via Type K thermocouple)

Note: VRM & inner case temperatures are always logged and if there are concerning results, they will be reported within the review. Otherwise, for simplicity’s sake results will be strictly kept to CPU-centric temperatures.

  CPU Cooler Fan Speeds

ASUS Default Fan Profile:

The default fan speed profile on the X299 Edition 30 dynamically modifies the fan speed (a percentage of the fan’s maximum RPM level) based on CPU package temperature. The levels are:

<40°C = 20% Fan Speed

>40°C / < 60°C = 20% to 55% Fan Speed

<60°C / < 80°C = 55% to 100% Fan Speed

> 80°C = 100% Fan Speed

Fixed RPM Modes: In an effort to normalize results while testing various noise levels & cooling potential the default fan profile is overridden with two separate fixed fan speeds. They are:

1000 RPMs – All cooler fans set to a constant 1000 RPMs regardless of their maximum RPM levels or CPU temperature

Full Speed Fans – All cooler fans are set to maximum level

AIO Considerations: While AIO coolers sometimes have built-in defaults with their shipping software, all default tests are conducted with their fans at the speeds indicated above. Meanwhile the pump speed is left at its stock level.

If the AIO does have specific preset performance profiles, they will be tested separately in its individual review.

  Reported Results & Acoustics

CPU Results:

All results in our charts are the stabilized CPU package temperature (as reported by HWInfo64) after 30 minutes of load. In addition, special care is given to monitor for any processor frequency throttling within that time span.

Optimally, our CPU would operate at maximum boost frequencies at stock and our predetermined fixed speed during the overclocking tests. Therefore, a cooler will fail a test (and we will indicate so within the charts) should speeds be lower than expected.

The thermal throttling conditions are:

Stock CPU: < 3.8GHz on any core Overclocked CPU: < 4.5GHz on any core

Acoustic Results: All acoustic results are done with a calibrated decibel meter placed at roughly 30” away from the closed test system and roughly at the same level an individual would be sitting when using the PC.

Like the temperature results all Acoustic results are logged once the 30 minute timer has expired.

As a general guideline, these are the approximate result outcomes:

< 35dB – Whisper quiet 35 – 40dB – Barely noticeable noise 40dB – 45dB – Noticeable noise > 45db – Loud

Note: For reference the test system with no CPU fans running and the 3x system fans at their constant 600RPMs measures a constant 32.8dB.

A muffler uses advanced technology to eliminate the noise. Is the muffler in your car damaged? This article will come in handy to help you understand all there is to know about muffler repair.

How much does it cost to repair a muffler?

The cost of repairing your muffler will depend on various factors such as the intensity of damage and the complexity of the task. If your muffler seems to be loose albeit functioning well, if you need to fix broken clamps, you may want to conduct small muffler repair professional who will offer the ideal guidance.

Small repairs on your muffler come at an average cost ranging between $30 and $500. Still, some people pay way less than the aforementioned rates. If you prefer getting a professional to replace your muffler, you will end up paying way more depending on your preferred type of vehicle.

Is Your Exhaust Faulty? Here are Some Quick Tips

What are Fuel Treatments?

What You Should Know About Replacement Parts

There are various types of replacement parts. You can either choose to purchase the original manufacturer produced replacement parts or simply go for the aftermarket parts which other companies produce. It’s worth noting that the former is more costly compared to the latter. Another factor that can influence cost is the person who executes the job.

If you’re working on a budget, choose small muffler shops within your locality which charge the least rates. Car dealership departments, on the other hand, are more costly. If other parts of your muffler system are up for replacement, you can prepare yourself to pay more with the average costs ranging from $1,000 and $2,500.

Common Muffler Problems

The cost of repairing a muffler depends on various factors such as the complexity of the exhaust problems. Here are some of the common muffler problems.

Blue, White, or Black Smoke Emanating from the Exhaust

Smoke will usually emanate from the exhaust. However, extremely thick or differently colored smoke can be an indication of problems with the car’s exhaust system. Often, smoky exhausts result from a warped or cracked cylinder head, a component located on the combustion chambers of your car’s engine which controls the flow of air and fuel and maintains the engine coolant. If the cylinder head is damaged, the coolant starts leaking in the hot engine causing huge smoke which is eventually driven out through the exhaust. The cost of repairing a cylinder head can be approximately $500. This price is inclusive of labor and parts.

Common Check Light Problems

Wheezing Sound from the Exhaust

A wheezing sound emanating from your vehicle’s exhaust system can be an indication of a leak or hole in the pipeline. If the leak is situated along with the catalytic converter, harmful gases will be generated in the atmosphere. Repairing your exhaust for this problem will cost anything between $125 and $300. However, the price could increase depending on the complexity of the problem.

A Popping or Rattling Noise Coming from the Exhaust

If your exhaust is producing a popping or vibrating noise as you drive, it could be because a bracket that supports part of the exhaust is loose. You can easily fix this problem if you detect it early at a reasonable cost of approximately $40. However, if you realize that the bracket is rotten, it could be an indication of a massive problem with the exhaust system in general. You mechanic could recommend an entire system replacement as compared to welding the bracket back in place.

Can you drive a car with a broken muffler?

The muffler is part of the exhaust system of your car and the entire exhaust system plays a major role in ensuring that your engine not only cuts down pollution but also maintains ultimate performance. If your muffler is extremely noisy, you should consult a mechanic. A poorly functioning muffler can raise various safety concerns as seen below.

Carbon Monoxide Poisoning

When there’s a hole in the muffler, carbon monoxide is likely to leak in the vehicle. Carbon monoxide is a toxic gas which can cause nausea, dizziness, and severe headaches. Prolonged exposure to carbon monoxide can cause unconsciousness and eventually death. If your car’s muffler system has a hole in it, you should desist from driving it and instead take it to a mechanic immediately.

Noise Pollution

Many cities across the world have noise regulations which regulate the extend of noisy mufflers, faulty mufflers included. Assuming your muffler is noisy albeit not faulty, driving it may not be dangerous. However, the police are highly likely to pull you overdue to noise pollution. To determine whether or not your muffler is faulty, you need to listen to any unusual sounds such as a vibrating sound in the exhaust system when the vehicle is running. When this happens, you need to call in the mechanic immediately and have him inspect your car.

Is Driving a Faulty Muffler Dangerous?

Yes. Driving your car with a faulty and loud muffler can be dangerous depending on the cause of the fault. If you notice any unusual sound or smoke emanating from your vehicle’s exhaust, you should have it inspected immediately.

How do you know if your muffler is bad?

A broken muffler will display various indications which will let you know that there’s a problem that may require replacement or repair of the muffler. Here are signs of a broken muffler that needs to be replaced.

Misfiring of the Engine

Technology has advanced greatly in recent years and the car industry has continued to evolve. Engines manufactured today are appropriately tuned machines and all components must collaborate to work efficiently and effectively. A vehicle’s exhaust system is one of these systems.

This system starts from the exhaust valve chamber located inside the cylinder head and flows through the exhaust headers, penetrates to the exhaust pipes, goes through the catalytic converter, the muffler, and goes out through the exhaust pipe. If any of these components is faulty or damaged, it can negatively affect the performance of the vehicle and even cause engine misfiring.

Condensation on the Exhaust Pipes

When the entire exhaust system is cooling down, moisture in the air thickens in the muffler and the exhaust pipe. The moisture settles there and slowly damages the shell of the muffler and the exhaust pipe. If this problem continues without the necessary measures being taken, the seams of your car’s muffler and exhaust pipe will rust away and gases will start leaking from the exhaust which results in increased noise.

If you notice excessive condensation emanating from the exhaust pipe more so during the warmer parts of the day, it could be an indication of a worn-out muffler. If you notice any of these problems with your muffler, you shouldn’t overlook them. Instead contact a qualified, reliable, and professional mechanic as soon as you can.

Can you get pulled over for having a loud muffler?

As we’ve seen above, muffler regulations vary in each country. In the US for instance, your car requires a muffler to be declared street legal. Further, each state and many local authorities and cities alike have regulations which prohibit excessively loud exhaust systems. Therefore, nearly every legally available car for sale comes complete with a certain legal street system. Still, many car owners may choose to enhance the performance of their cars by installing an aftermarket exhaust system. If you’re among them, you could be worried that your car’s exhaust system surpasses the legal noise levels.

What are the Regulations for Maximum Muffler and Exhaust System Sound?

Unfortunately, there are no national laws that exhaust manufacturers and vehicle owners can refer to ensure that their systems adhere to the permitted noise levels. Rather, each vehicle exhaust system installer and vehicle owner should be conversant with the laws within their locality. In California for instance, the maximum vehicle exhaust sound limit is 95 decibels when evaluated next to the vehicle.

The laws in Kansas are slightly lenient with the vehicle exhaust noise limit should be less than 90 decibels when evaluated 50 feet away from the vehicle. It’s worth noting that the further sound travels, the more it deteriorates. This means that exhaust systems in Kansas can be louder than in California.

Locals can Devise their Own Rules

The local communities in many of the big cities across the world can devise their rules that further limits sound levels. Perhaps many of them can borrow a leaf from New York City where drivers can be flagged down if the exhaust system in their vehicles is inaudible. The maximum legalizes exhaust sound limit is 86 decibels.

Today even as the world and city streets become congested, some cities are adopting rules to guarantee silence while preventing any excessively loud exhaust systems from running between 11 am and 6 am. Again, you need to understand that you can only measure sound levels using a calibrated decibel meter, a gadget that’s not featured in many police cars.

What to Do When Charged for an Excessively Loud Exhaust System

If the police pull you over and proceed to charge you for driving a car with an extremely loud exhaust system, you can easily challenge the case in court, especially if the officer who charged you never used a calibrated meter.

Understanding the Existing Exhaust System Regulations

As we’ve seen above, there are no noise level regulations. However, there are some basic regulations which apply to all vehicles in all the localities and states as seen below.

Attempting to modify the existing muffler in your car to make it louder is prohibited. This law is in place to ensure that car owners don’t generate an exhaust leak which can be dangerous to humans and the environment.

Removing the catalytic converter is prohibited. Some people opine that the catalytic converter limits exhaust flow which isn’t the case more so for new model catalytic converters in the market that are specially designed for performance.

Driving a vehicle that lacks any type of muffler is illegal. Open pipes are illegal across the world.

Backfires are highly against the law and you can be pulled over and charged, if the police notice that your vehicle has a mechanical fault resulting in regular engine backfires. Re-routing your car’s exhaust system via the passenger’s side of your vehicle is illegal.

Finally

If you own a vehicle, you need to understand all the exhaust system regulations within your locality. If a police officer ever stops you for violating these regulations, first ask them whether they’ve measured the car’s noise levels using a calibrator and if you establish they didn’t, you can use the evidence to defend yourself in court. Remember, the muffler is an essential part of your car and you should conduct regular maintenance services on it not only to ensure that it’s functioning well but also to prolong its lifespan. These tips should help you manage your exhaust pipe efficiently.
