Abstract:

ANSI S3.44-1996 is a valuable tool for the audiologist to use when reviewing individuals' audiometric records within occupational hearing conservation programs, as well as when evaluating claimants for Worker's Compensation or hearing-related legal actions. By comparing the amount of hearing loss for an individual to the predictions of the model in the standard, the professional can more objectively assess the probable contribution of workplace noise to the individual's total hearing impairment. Likewise, by comparing the time course of the development of loss as shown in hearing conservation program audiograms to model predictions, one can better judge the probability that occupational noise may have caused a recent hearing change (such as an OSHA STS). Examples of actual cases will be shown to illustrate the steps involved in these applications of the standard.
