2Measuring Noise Exposure as Sound

Noise Dosimeters are useful in measuring noise exposures. Think of them as an expensive sound level meter with an internal clock that adds up all the dangerous sounds you are exposed to while wearing the device. It is a little box with a microphone that you wear on your body, usually clipped on a shoulder.

The noise dosimeter will report the average number of decibels you were exposed to and the “dose” of noise that occurred. Anything over a 100% dose indicates that a person’s exposure to high-level sound that day was too much.
