A STUDY OF THE EFFECTS OF GUNFIRE AND OTHER INFANTRY COMBAT TRAINING NOISES ON THE HEARING ACUITY OF U.S. MARINE CORPS RECRUITS

Abstract

An investigation was made of the effects of short periods of exposure to impulse noises on hearing acuity. Hearing data were obtained from U. S. Marine Corps Recruits before and after exposures to gunfire and other infantry combat training noises. The results indicated that (1) small arms and combat training noises were responsible for loss of hearing acuity for test frequencies above 2 kc with the most pronounced mean threshold shift at 6 kc, (2) ear protection was sufficient to prevent these changes during small arms gunfire exposures, and (3) hearing lossesAFTER INFANTRY COMBAT TRAINING EXPOSURES WERE QUITE SIMILAR TO TEMPORARY THRESHOLD SHIFTS MEASURED IMMEDIATELY FOLLOWING RIFLE RANGE ACTIVITIES.
