Abstract
A study was performed to develop a noise generation system for modeling complex industrial noise environments; to develop analysis algorithms to extract metrics from the noise that would be highly correlated with trauma produced by exposure to that noise; and to initiate animal model studies that would demonstrate the need for new metrics as well as the applicability of new metrics that would be extracted from the noise. The authors note that the most significant results of their 3 year study were that complex noise environments are not adequately described for the purpose of hearing conservation by using time averaged metrics. They note as well that the statistical properties of a noise environment are important in determining acoustic trauma. When comparing the audiometric and histological data to metrics based on kurtosis measured in the time and frequency domains, a clear indication is offered that these metrics in conjunction with Leq predict well the relative magnitude and frequency distribution of acoustic trauma.
