Abstract
Abstract : Three studies of unaided auditory localization of a helicopter are summarized. In each, a UH-1B helicopter in flight was the sound source and was localized by subjects on the ground. Absolute mean angular errors of different groups and under different conditions ranged from 8 degrees to 24 degrees and more, with smaller errors found under quieter conditions and at greater target ranges. Error size was not significantly affected by: flight direction; altitude changes from low nap-of-the-earth (20 - 60 feet) to low contour (100 - 110 feet); interfering noises from 90-mm gunfire; or wearing a combat helmet. There were significant differences associated with interfering noise from passing vehicles and with subjects' auditory acuity.
