Application of Noise Certification Regulations within Conceptual Aircraft Design [PDF]
ICAO Annex 16 regulations are used to certify the acoustic performance of subsonic transport aircraft. Each aircraft is classified according to the measured EPNL levels at specific certification locations along the approach and departure.

Toward Noise Certification during Design: Airframe Noise Simulations for Full-Scale, Complete Aircraft. [PDF]
An overview of a recent, NASA-sponsored effort to substantially advance simulation-based airframe noise prediction is presented. An accurate characterization of this component of aircraft noise requires a high-fidelity representation of the finer geometrical details associated with the landing gear and wing high-lift devices, such as slats and flaps ...

Data-Driven Certification of Neural Networks With Random Input Noise [PDF]
Methods to certify the robustness of neural networks in the presence of input uncertainty are vital in safety-critical settings. Most certification methods in the literature are designed for adversarial or worst-case inputs, but researchers have recently shown a need for methods that consider random input noise.

Comparison of predicted engine core noise with current and proposed aircraft noise certification requirements [PDF]
Predicted engine core noise levels for subsonic CTOL aircraft engines are compared with measured total aircraft noise levels and to current and proposed federal noise certification requirements. Comparisons are made at FAR-36 measuring stations and take into consideration both full and cutback power operations at takeoff.
