USAF Bioenvironmental Noise Data Handbook. Volume 6. A/M32A-60 Generator Set, Power Unit.
Abstract
The A/M32A-60 Generator Set is a gas turbine engine driven source of AC/DC electrical power with pneumatic capability. 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. Near-field data are reported for 37 locations in 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. 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 for these same seven acoustic measures as functions of angle and distance from the source.
