Functions of hearing aids

A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one.A hearing aid has three basic parts: a microphone, an amplifier, and a speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss that results from damage to the small sensory cells in the inner ear, called hair cells. This type of hearing loss is called sensorineural hearing loss. The damage can occur as a result of disease, aging, or injury from noise or certain medicines.A hearing aid magnifies sound vibrations entering the ear. Surviving hair cells detect the larger vibrations and convert them into neural signals that are passed along to the brain. The greater the damage to a person’s hair cells, the more severe the hearing loss, and the greater the hearing aid amplification needed to make up the difference. However, there are practical limits to the amount of amplification a hearing aid can provide. In addition, if the inner ear is too damaged, even large vibrations will not be converted into neural signals. In this situation, a hearing aid would be ineffective. If you or an adult family member have questions or concerns about hearing loss, you have options. Over-the-counter (OTC) hearing aids are a new category of hearing aids that people can buy directly, without visiting a hearing health professional for an examination. These hearing aids are intended to help adults with perceived mild to moderate hearing loss. Prescription hearing aids are available from a hearing health professional who will program them for your degree of hearing loss. Prescription hearing aids or other devices may be necessary for more significant or complicated hearing loss. Spieth's latest H51 is an OTC hearing aid, the appearance is mini and exquisite, easy to carry, the core is "powerful", and the maximum fitting range is over 80dB. And the price is very friendly.

Why are open-fit hearing aids so popular?

Open-fit hearing aids are styles that do not block the ear canal. Despite their resurgence in popularity in recent years, open-fit hearing aids are not new. The main reason they're back in fashion is that their biggest problem -- feedback -- isn't a big deal anymore. Even basic hearing aids now have advanced feedback management systems that can help detect and eliminate it before it reaches your ears. Natural listening experience In addition to eliminating feedback, open-fit hearing aids also provide a more natural listening experience. Instead of the "barrel effect", the sound is free to move around the receiver and into the ear canal. This allows you to hear background noise naturally, while the sounds you most need to hear clearly, such as voices, are fed through your hearing aids. No custom accessories required Open-fit hearing aids also do not require ear molds. Because audiologists don't have to take an impression of your ear and send it to a custom fit, they can fit your hearing aids right in the office. You might even leave with them on the same day. This is an ideal feature for those who have hard-to-fit hearing aids or just want to reduce the hassle. Cosmetic appeal and durability The shell of an open hearing aid is carefully placed behind the ear, with a small tube connecting it to the ear canal. Many people find this style more aesthetically pleasing than styles with ear molds or visible outside the ear. Because hearing aid components are installed further from the ear canal, they are also less susceptible to damage from moisture and earwax. This can prolong the life of the hearing aid.
