AIRCRAFT NOISE REDUCTION

This paper describes the acoustical treatment used in the engine nacelles on DC-10 airplanes. The special acoustical features of the cabin sidewall insulation and the airplane's interior panels are also described. Results of incorporating these various noise-control features are given in terms of flyover noise levels during takeoff and landing and in terms of cabin noise levels during cruise.
