New American National Standard: Methods for the Measurement of Noise Emissions from High Performance Military Jet Aircraft

摘要

Noise emissions from high performance military aircraft (supersonic jet flow exhaust) can impact the hearing and performance of personnel working near these aircraft and can be a source of annoyance to people living near airbases, airports, and ranges where these aircraft are operated. Federal agencies operating airfields are required to assess the potential noise impacts and to regulate flying operations based on measured and predicted noise metrics. An American National Standard was developed for the accurate, reliable, and repeatable measurement of noise emissions from high performance military aircraft. The standard describes the measurement procedures of ground run-up, flyover, and short/vertical takeoff and landing operations. The procedures and jet noise models used to assess community impact in this standard will be discussed.
