Hearing Losses of Personnel Exposed to Impulse and Steady State Noise

Abstract

Hearing losses of personnel exposed to impulse and steady noise for 1 to 79 months are of the same magnitude and type. For those who are exposed over 80 months, steady noise exposure appeared to produce somewhat greater hearing losses than impulse noise. Apparent screening effects were noted in the 1-to-39- and 40-to-79-month exposure groups.
