USAF Bioenvironmental Noise Data Handbook. Volume 18. A/E 24U-8 Power Plant, Electric, Gas Turbine.
Abstract
The A/E24U-8 Power Plant supplies precise power for 3-D radar, computers and communications for the Tactical Command System 407L. This unit includes tow generator sets (EMU-30E) which can be operated singly or in parallel. 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 38 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 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.
