ATEFA - Project's results on UAM air traffic noise and air-taxi certification
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023ATEFA, Germany's first nationally funded research project on UAM community noise, aimed to provide first answers, how novel air traffic noise from air-taxis can be assessed in a realistic scenario.

Atmospheric Absorption Model Effects on Civil Rotorcraft Noise Certification EPNL Values
Proceedings of the Vertical Flight Society 73rd Annual Forum, 2017Different atmospheric absorption models are applied to noise certification measurements for the Bell Models 429 and 505. It is shown that the latest atmospheric absorption model proposed for use in rotorcraft noise certification, SAE ARP5534, yields ...

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

Helicopter noise certification
Applied Acoustics, 1988Abstract The object of noise certification is to reduce aircraft noise at source by incorporating internationally agreed limits into national civil airworthiness requirements. The operation of aircraft which fail to comply with these limits during type tests is prohibited, providing manufacturers with a powerful incentive to design quieter machines ...

Flexible Noise Based Robustness Certification Against Backdoor Attacks in Graph Neural Networks
International Conference on Information Systems Security and Privacy: Graph neural networks (GNNs) are vulnerable to backdoor attacks. Although empirical defense methods against such attacks are effective to some extent, they may be bypassed by adaptive attacks.

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.

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 ...
