Alternative noise certification concepts for air carrier aircraft

The Journal of the Acoustical Society of America, 1980
This paper examines a number of general and specific concepts in noise certification. These include current takeoff and landing flight procedure requirements, and the potential role of static engine noise testing for noise certification. Effectiveness of existing noise certification concepts are briefly reviewed and alternative methods considered which

Aircraft Noise Certification Requirements Which Ensure Use of Available Noise Control Technology

Noise Control Engineering, 1976
The 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 ...
