Abstract
Industrial noise environments ae frequently characterized by combinations of noise impacts superimposed on a steady-state continuous noise background. Digital techniques were used to synthesize complex noise environments containing random impulses with random peak SPL's up to 125 dB. Four groups of chinchillas we exposed to one of three different complex noise environments whose sound exposure levels and spectra were similar to a fourth Gaussian Noise Exposure. Conventional methods were used to measure energy spectra and exposure levels. Measures of permanent threshold shift showed significant differences between the complex noise exposures and the Gaussian exposure. An application of frequency domain kurtosis [R. F. Dwyer, IEEE J. Oceanic Eng. OE-9, 85-92 (1984)] emphasized the region of the noise spectrum where audiometric differences we measured.
