Hearing levels in U.S. Army engineers
Abstract:
An 18-item questionnaire on otoaudiological and noise-exposure history was completed by over 900 U.S. Army engineers, of whom reference and current audiograms were collected on 209 Ss who reported no obvious ear or hearing problems and did not participate in non-military noise-hazardous hobbies or activities. Subgroups of 6 military occupation specialties were studied separately; differences among these were unremarkable in age, length of military service, and job-related noise exposure, in current HTLs and in hearing losses re reference audiogram prior to appreciable military noise exposure. Mean current HTLs were better 3, 4 and 6 kc/s by about 23, 34, and 24 db (L + L ears) than a comparably-aged group of 450 men working in industry (Glorig et al, 1957). These results augur well for the current Army hearing conservation program.

Sound Intensity Level
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
