Aircraft Noise Certification Requirements Which Ensure Use of Available Noise Control Technology
Phlébologie, 1976The results of compliance demonstration test programs for new wide-bodied aircraft powered by high-bypass-ratio engines showed that in some cases the aircraft noise levels were well below those of the requirements. This prompted a number of investigations, both in the US and internationally, to determine the feasibility of modifying the noise ...

STOL Aircraft Noise Certification-A Rational Approach
SAE Technical Paper Series, 1970<div class="htmlview paragraph">Government and industry representatives are currently at work formulating a rule for certifying the noise levels of short takeoff and landing (STOL) aircraft. Conventional aircraft are primarily turbofan propelled and fly over well-defined landing or takeoff paths at conventional airports. In contrast to this, STOL

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023
OEMs are required to meet applicable regulations for exterior noise. Acceleration noise (typically called pass-by noise) regulations have an upper limit for noise emission. In addition, vehicles which can operate without a combustion engine must comply with regulations for minimum noise emitted during low speed driving.

Noise Certification of Business Jet Aircraft
SAE Technical Paper Series, 1971<div class="htmlview paragraph">Noise certification under FAR Part 36 is now a requirement for issuance of all new and supplemental type certificates for turbojet-powered or transport-category aircraft. Recent experience with three noise certification programs has shown: how to estimate from aircraft performance data the necessity and extent of ...

Aircraft Noise Certification Procedures in Retrospect; 1969-1976
SAE Technical Paper Series, 1976<div class="htmlview paragraph">Procedures for measurement and evaluation of aircraft noise are contained in FAR Part 36 which was formulated in the late sixties. Over six years experience with this regulation has resulted in more than 5000 noise certification actions on the Boeing family of commercial jet transports.
