Aircraft Noise Definition.

Abstract

Acoustic data acquisition and reduction systems are discussed together with analytical procedures used to derive noise characteristics of a series of Boeing aircraft types. Noise data are presented in EPNdB and dB(A) units, from takeoff to low approach thrust and for aircraft altitudes from 200 to 12,000 feet. Areas of possible data deficiency are identified and 90% confidence limits established where possible. A flight test program is proposed with the objectives of improving data accuracy and establishing confidence limits over a wide range of operating conditions.
