More Book Details

Description of the Book:

The USMC AV-8A is a V/STOL light-attack aircraft powered by one F402-RR-401 turbojet engine. This report provides far-field measured and extrapolated data defining both physical and psycho-acoustic measures of the bioacoustic environments produced by this aircraft operating on a ground runup pad for two power conditions and in two hover modes (50 and 100 feet above ground level). Far-field data measured at 17 locations are normalized to standard meteorological conditions and extrapolated from 75-8000 meters to derive sets of equal-value contours as a function of angle and distance from the source. These contours are measures of: 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. Refer to Volume 1 of this handbook, USAF Bioenvironmental Noise Data Handbook, Vol 1: Organization, Content and Application, AMRL-TR-75-50(1) 1975, for discussion of the objective and design of the handbook, the types of data presented, measurement procedures, instrumentation, data processing, definitions of quantities, symbols, equations, applications, limitations, etc.
