Environmental Noise Assessment for Military Aircraft Training Routes. Volume 1. SAC (Strategic Air Command) Low-Level Routes.
Abstract
A series of noise measurements was conducted underneath a low-altitude military training route utilized by SAC aircraft. The primary measurement system consisted of 17 automatic noise monitors deployed on a two-mile array across the route. These recorded A-weighted noise metrics and provided identification of the lateral position of each aircraft. Data were obtained for 48 aircraft over a 15-day period. It was found that maximum A-weighted sound levels and sound exposure levels for B-1 and B-52 aircraft agreed well with predictions from the Air Force's existing NOISEFILE data base. It was also found that the distribution of lateral position re: centerline well described by a Gaussian distribution with a standard deviation of 0.5 mile. Analog recordings were made of selected overflights of B-1, B-52, and FB-111 aircraft. These provided definition of the temporal and spectral characteristics of these flight operations. Keywords: Military aircraft operations; Community noise exposure; Bomber aircraft.
