Noise Meter

Play around with the Noise Meter and hear the different sounds and sound intensities of everyday objects. 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 intensity of about 110 dB. Without proper hearing protection, running a chain saw for only 2 minutes can become dangerous to the human ear!

sound meter ranging from 85 to 112 db
