PROPELLER AIRCRAFT NOISE AROUND GENERAL AVIATION AIRPORTS

A method is presented to compute Leq noise contours for propeller driven general aviation airplanes within a reasonable amount of computing time. In this method, approximations are used to account for the effects of engine power and propeller rpm, for the nonspherical noise radiation of these airplanes and for atmospheric attenuation on the single event exposure levels, observed on the ground. Noise data are based on a large body of flyover noise field measurements. Measurement and data reduction procedures are briefly described and illustrated. Leq noise contour plots are used to evaluate the effects of three approaches to reduce noise levels on the ground around a general aviation airstrip: increasing circuit altitude, rerouting, and noise reduction at the source. The last, which is by far the most effective, will require a considerable amount of additional research and money. Short-term solutions to noise problems may be obtained by routing aircraft away from noise-sensitive areas. Increasing the circuit altitude is generally not very effective.
