Human Performance Criteria for Military Noise Exposure
Abstract
A new research program is described whose objectives include: identification of aural performance requirements of soldiers in tactical situations; quantification of the effects of aural acuity deficits on such performance; and development of models to predict the effects of military noise exposure on soldiers' performance. It is shown that soldiers need to be able to hear in the 100 Hz to 12 kHz range. Hearing losses are usually first observed at 4-6 kHz. Speech reception is relatively unaffected by typical hearing loss patterns, and can be predicted fairly well from audiometric data. Materiel sound detection is unaffected by typical hearing losses. Personnel sound detection is probably affected by typical hearing losses, and cannot be predicted from audiometric data. The program's current emphasis is on the relation between hearing acuity and high-frequency personnel sound detection. A description of the test environment is included.
