TL;DR: Data on aircraft annoyance from a French study of 1965–1966 have been re-evaluated in the light of findings from a recent Scandinavian study and show that reduction of noise of individual aircraft is of primary importance in reducing annoyance.

TL;DR: Maris et al. as mentioned in this paper showed that noise annoyance increases due to unfair sound management, however only when the sound pressure level is high, concluding that being exposed to manmade sound is more than mere exposure: it is a social experience, too: You expose Me.
Abstract: Unfairness increases noise annoyance
Noise annoyance increases due to unfair sound management. Fair sound management reduces annoyance, however only when the sound pressure level is high, concludes Eveline Maris based on two laboratory experiments.
Being exposed to man-made sound is more than mere exposure: it is a social experience, too: You expose Me. This social hypothesis of noise annoyance has been confirmed in two laboratory experiments. Participants were exposed to aircraft noise (sound pressure level (SPL): 50 or 70 dB A) and treated either in a neutral, fair, or unfair manner. The results show that besides SPL, also the fairness of the procedure determines the level of noise annoyance. The first experiment shows an interaction effect of procedural fairness and SPL: annoyance ratings are significantly lower in the fair than in the neutral condition, but the effect is found only when SPL is 70 dB. The second experiment shows a main effect of procedural unfairness on noise annoyance: annoyance ratings are significantly higher in the unfair than in the neutral conditions, regardless of SPL.
The findings imply that, in addition to noise reduction engineering, application of knowledge on the social side of noise annoyance can help reduce future noise annoyance levels.

TL;DR: The capabilities of the current suite of synthesis and simulation tools, their application to fixed and rotary wing aircraft, and some directions for the future are discussed.
Abstract: The NASA Langley Research Center is involved in the development of a new generation of synthesis and simulation tools for creation of virtual environments used in the study of aircraft community noise. The original emphasis was on simulation of flyover noise associated with subsonic fixed wing aircraft. Recently, the focus has shifted to rotary wing aircraft. Many aspects of the simulation are applicable to both vehicle classes. Other aspects, particularly those associated with synthesis, are more vehicle specific. This paper discusses the capabilities of the current suite of tools, their application to fixed and rotary wing aircraft, and some directions for the future.

TL;DR: In this paper, the authors discuss the environmental impact of road, rail and air transport, together with ground borne vibration generated by road and rail vehicles and the overall noise effects of all three transport modes.
Abstract: This book discusses the environmental impact of road, rail and air transport. The effects of air pollution from road traffic are evaluated, together with ground borne vibration generated by road and rail vehicles and the overall noise effects of all three transport modes. The loss of visual amenity resulting from road construction schemes is also considered. The subject matter is treated under the following chapter headings: (1) impact assessment for transport proposals; (2) highway traffic noise; (3) predictions of highway noise; (4) road traffic noise control; (5) aircraft noise; (6) train noise; (7) atmospheric pollution. The principles of acoustics are appended, together with details of human response to, and insulation against noise. /TRRL/
