An Industrial Noise Map Is Basic to Hearing Conservation
In the U.S., OSHA has set regulations on worker noise exposure. The usual measurement method is to use a portable noise dosimeter attached to a worker that measures noise exposure as the person moves about the work area. However, this does nothing to identify the source and location of the noise. When conducing a noise survey, a noise map is the most useful means of identifying noise sources and where the noise exposure may be greatest.
