Abstract:

The USN S-3A aircraft is for anti-submarine warfare and is powered by two TF34-GE-2 turbofan engines. This report provides far-field measured and extrapolated data defining both physical and psychoacoustic measures of the bioacoustic environment produced by this aircraft operating on a ground runup pad for four enginepower conditions. Far-field data measured at 17 locations are normalized to standard meteorological conditions and extrapoderive 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.
