Noise Survey Instruments
Noise Dosimeter
A dosimeter is like a sound level meter except that it stores sound level measurements and integrates these measurements over time, providing an average noise exposure reading for a given period of time, such as an 8-hour workday.
Dosimeters can be used to:
- Make compliance measurements according to OSHA's noise standard.
- Measure the employee's exposure to noise and automatically compute the necessary noise dose calculations.
With a dosimeter, a microphone is attached to the employee's clothing and the exposure measurement is simply read at the end of the desired time period. A reader may be used to read-out the dosimeter's measurements. Since the dosimeter is worn by the employee, it measures noise levels in those locations in which the employee travels.
