Did You Know? What is an Anechoic chamber?

The world's quietest room is located at Microsoft's headquarters in Washington. It's an anechoic chamber designed to absorb almost all sound, reaching a level of quietness of -9 decibels. That's quieter than human breathing! Scientists use this room to test products for noise reduction and to study the effects of silence on the human body. Imagine a world so quiet you can hear your own heartbeat!
