Acoustics. Estimation of noise-induced hearing loss1 Scope This International 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
