USAF Bioenvironmental Noise Data Handbook. Volume 30. MD-3A Generator Set.
Abstract
The MD-3A Generator Set is a portable unit designed to furnish AC and DC current for starting aircraft, for ground maintenance, and for servicing and calibrating instruments. This report provides measured and extrapolated data defining the bioacoustic environments produced by this unit operating outdoors on a concrete apron at normal rated/loaded conditions. Far-field data measured at 36 locations are normalized to standard meteorological conditions and extrapolated from 10-1600 meters to derive sets of equal-value contours as functions of angle and distance from the source for a wide variety of physical and psychoacoustic measures: overall and band sound pressure levels, C-weighted and A-weighted sound levels, preferred speech interference level, perceived noise level, and limiting times for total daily exposure of personnel with and without standard Air Force ear protectors.
