Abstract
Personal noise dosimetry monitoring devices have been used for some time by various Air Force bases to determine the occupational noise exposures of Air Force personnel. In May 1978, Aerospace Medical Research Laboratory began consolidating noise dosimetry data from these bases. The author has personally collected data during the past year on visits to four Air Force bases. Over 418 separate 8‐h occupational noise exposure measurements were made on 120 different people. Some of the research involved 16 people wearing a dosimeter for 1 day or up to a week at a time. Seventy‐three separate 24‐h measurements were made. From these data a comparison was made between the off‐duty noise exposures and the work‐related noise exposures. The individual's work‐related noise exposure (except in a few instances) contributed the highest noise levels to the person's 24‐h noise dose. The 24‐h noise levels ranged from 60 to 92 dBA with a median level of 77 dBA. Previous studies supported by AMRL have shown a median level of 75 dBA for the typical American. This paper will discuss the basis of the AMRL research, as well as the merits of noise dosimetry and some of the problems encountered during the study. [Work supported by EPA and USAF.]
