A PILOT STUDY OF TEMPORARY THRESHOLD SHIFTS RESULTING FROM EXPOSURE TO HIGH-TENSITY IMPULSE NOISE

Abstract

This investigation was a pilot study to determine the temporary threshold shift resulting from exposure to high-intensity impulse noise. The threshold shifts induced were of a temporary nature, i.e., there were no instances of permanent hearing losses along any of the experimental subjects. The purpose was to explore various physical parameters of a sound source and relate them to any decrements they may have on auditory acuity. Thirty enlisted men received audiometric tests both before and after exposure to a high-intensity impulse noise generated by an M-14 rifle. Rate and number of impulses w re varied separately and examined at three test frequencies. Due to inter-subject differences, only general implications are indicated. Recommendations are included for future research.
