Important note : Users cannot be edited or removed once added to your Multi user PDF.This American National Standard specifies a method for calculating the expected noise‐induced permanent threshold shift in the hearing threshold levels of adult populations due to various levels and durations of noise exposure; it provides the basis for calculating hearing disability according to various formulae when the hearing threshold levels at commonly measured audiometric frequencies, or combinations of such frequencies, exceed a certain value.
