Noise Meter

Play around with the Noise Meter and hear the different sounds. The red bar below shows how long it takes before a particular sound level becomes dangerous to the human ear. For example, a chain saw has a sound level of about 110 dB. Without proper hearing protection, running a chain saw for only 2 minutes can become dangerous to your hearing!
