Research approaches to alleviation of airport-community noise

Abstract The material of this paper relates to the problem of noise in communities near commercial airports due to landing and take-off operations and contains a description of some of the related NASA sponsored research toward its alleviation. The objectives of the paper are to identify some of the significant factors involved, and to present pertinent research information from NASA in-house and contract studies. Data are included to illustrate the significance of such factors as aircraft engine type, compressor configuration, nacelle location and design, power reductions during climbout, steep angle landing approach profiles, and compatible land usage, with regard to noise alleviation and human response implications.
