Abstract
Introduction: Exposures to noise and the simple act of ageing have negative consequences for hearing sensitivity: both result in loss of hearing. When studies have been conducted to determine the effect of either ageing or noise exposure on hearing, the primary task has been sort out the hearing impairment due to each. There are two standards (3,2) that propose methods for predicting the impact of noise exposure on hearing. Each standard provides reference databases; ANSI S3.44 included the two databases contained in ISO 1999 plus one additional. Just as these standards allow prediction of hearing loss due to ageing and noise exposure, their equations may also be used in reverse to determine the amount of noise that would be responsible for an observed, age-corrected hearing loss. These noise levels may then be compared to observed noise exposures in order to determine the accuracy or error of the standards. As well, this procedure may suggest modifications to the standards= equations may be in order.
