INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2021
Several studies predict an increase up to 40% in traffic flights by the 2040. Airport noise control is a complicated procedure which creates an interesting blend of science, politics, and money. Accordingly, in many communities where airport noise is perceived as a significant problem, a noise control program is sometimes viewed as a continual process,

Aircraft magnetic noise sources
8th International Congress of the Brazilian Geophysical Society, 2003Aeromagnetic aircraft and data acquisition systems generate magnetic interference which can effect the quality of the data collected. Many people believe that traditional aircraft compensation, which models the permanent, induced, and eddy-current sources, can remove all of this interference.

Physics Bulletin, 1972
Without wishing to detract from the merit of Prof J B Large's article on aircraft noise in the November 1971 issue of Physics Bulletin, we would like to draw attention to a potential danger arising from one of his recommendations. His first recommendation, to replace the existing NNI expression by a logarithmic form of the expression deserves support ...

Aircraft Noise traces the origins of this problem to the introduction of the jet engine into the airline fleet in the late 1950s and describes the legal restrictions now placed on the industry. It explains the derivation of the special noise units and assessment scales now used around the world; noise exposure modeling and forecasting; the major ...

An aircraft noise adaptation model is being developed at Langley Research Center to account for the variability in the responses of subjects participating in noise experiments. The principal concept of the model is a measured “aircraft adaptation level” which represents a noise annoyance calibration for each individual. The model assumes that annoyance

Although it has been generally accepted that noise control is of great importance around airports, little consideration has been given to the instrumentation concept. The purpose of this article is to discuss various requirements to noise monitoring systems with respect to flexibility, reliability and operation.

Noise has been an issue for airport communities and passengers since the advent of commercial air transport almost a century ago. Impressive gains have been made in aircraft noise control, but expectations are rising and air traffic will at least double in the next 20 years. Also, lighter composite structures pose a challenge for interior noise control.

Journal of Sound and Vibration, 1996
Significant advances have been made during the past 45 years in the understanding of airplane interior noise. Noise sources and transmission paths are discussed, and methods for the prediction of interior noise are summarized. Noise control methods are reviewed, including recent work in active noise control.

Flight Operational Noise Internationally, noise due to flight operations in the vicinity of airports. Each nation has developed an individual system of assessment and criteria for judging acceptability or probable extents of annoyance arising from the community based on local conditions and experience.
