NOISE ENVIRONMENTS WITHIN MULTIPLACE FIXED-WING AIRCRAFT.

Abstract

Noise environments within various multiplace fixed-wing aircraft demonstrate differences related to the proximity of the occupant to primary and secondary noise-generating mechanisms. The report defines acoustic environments sampled at different locations within eight groups of fixed-wing aircraft during conditions of normal cruise. A total of 51 aircraft, representative of vehicles powered by reciprocating, turbopropeller, and turbojet or turbofan engines, provided the data from which 28 noise envelopes were plotted. (Author)
