Description

ASA S12.19 – American National Standard for Measurement of Occupational Noise Exposure.

This standard is an adaptation of the international standard ISO 1999:1990(E) of the same name. Unlike the internationalstandard, this standard allows assessment of noise exposure using a time/intensity trading relation other than a 3-dB increaseper halving of exposure time. This standard presents, in statistical terms, the relationship between noise exposure and changes inhearing threshold levels for a noise-exposed population. This standard can also be applied to the calculation of the risk ofincurring hearing handicap from sustained daily exposure to noise. Guidance is provided as to the measurement of noiseexposure.
