ASA S3.44-1996 (R2006)
American National Standard Determination of Occupational Noise Exposure and Estimation of Noise-Induced Hearing Impairment
standard by American National Standards of the Acoustical Society of America, 01/01/1996
Full Description
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-decibelincrease per halving of exposure time. This standard presents, in statistical terms, the relationship between noise exposures andchanges in hearing threshold levels for a noise-exposed population. This standard can also be applied to the calculation of therisk of incurring hearing handicap from sustained daily exposure to noise. Guidance is provided as to the measurement of noiseexposure.
