USAF Bioenvironmental Noise Data Handbook. Volume 16. NF-2 Floodlight Set.
Abstract
The NF-2 Floodlight Set provides portable floodlighting facilities for aircraft maintenance on ramps where commercial power is not available, or for utilization as emergency lighting in disaster areas. 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.
