Abstract:

The study is designed to display the percent of a population exhibiting greater than certain specified audiometric hearing levels as a function of specified exposure levels and duration of exposures to those levels. Audiometric data from 6835 employees of an industrial plant were taken during the period from 1960 through 1965. The employees were selected only on the criterion that their noise exposures were reasonably well known. Hearing levels for each of three exposure conditons 78, 86, and 92 dBA were obtained for the speech 0.5, 1, and 2 kHz and the 4 kHz audiometric frequencies. The data are smoothed and hearing risk tables are presented.
