Community Noise Exposure Resulting from Aircraft Operations. Volume 5. Acoustic Data on Air Force Propeller Aircraft
Abstract
This series of reports present the results of field test measurements to define the noise produced on the ground by military, fixed wing aircraft during controlled level flyovers and ground runups. For flight conditions, data are presented as a function of angle and distance to the aircraft. All of the data are normalized to standard acoustic reference conditions of 59 F temperature and 70% relative humidity. Volume 1 discusses the scope, limitations, and definitions needed to understand and use the volumes containing the noise data. It provides guidance for making airspeed and engine power setting adjustments to the flight noise data for other than reference conditions as well as work sheets and several examples for computing cumulative noise exposure resulting from multiple flight or ground runup operations. Noise data are presented in this Volume 5 for the following Air Force propeller type aircraft: C-7A; C-97L; C-118A; C-119L, C-121C, G, S, T; C-123K; C-130A, D; C- 130B, E; C-130H, N, P; C-131A, B, D, E; OV-10, T-29; and U-4B.
