TLDR
In this article, the authors found that sound exposure levels of individual noise intrusions were much more closely associated with awakenings than long-term noise exposure levels, and the slope of the relationship between awakening and sound exposure level was rather shallow.Abstract:
Behaviorally confirmed awakenings were recorded during nighttime hours for periods of approximately one month in 45 homes of 82 test participants. Measurements of awakening and of both indoor and outdoor noise exposure were made for a total of 632 subject nights near a military airfield, 783 subject nights near a civil airport, and 472 subject nights in neighborhoods with community noise exposure of nonaircraft origin. Sound exposure levels of individual noise intrusions were much more closely associated with awakenings than long‐term noise exposure levels. The slope of the relationship between awakening and sound exposure level was rather shallow, however. Although the present findings do not resemble those of laboratory studies of noise‐induced sleep interference, they are in good agreement with the results of other field studies.read more

What Is so Special about Shoebox Halls? Envelopment, Envelopment, Envelopment
TL;DR: The authors of as mentioned in this paper identified quantitative factors that contribute to hall quality, such as listener envelopment, that is, the sense of being surrounded by sound, in particular, in the time period greater than 80 milliseconds after the arrival of the first sound; reverberant character, usually quantified in terms of the reverberation time; diffusion, an important factor contributing to envelopment; sound strength, as determined by taking measurements at various seats throughout the hall of sound delivered from a rectangular shape.
Sleep disturbance due to noise: Research over the last and next five years
TL;DR: This brief review will consider some fundamental issues concerning noise and sleep disturbance, outline some of the developments over the last five years and consider the continuing and emerging issues with some suggestions how research will develop in the future.

Enhanced awakening probability of repetitive impulse sounds.
Joos Vos,M.M.J. Houben +1 more
TL;DR: In the present study relations between the level of impulse sounds and the observed proportion of behaviorally confirmed awakening reactions were determined and various explanations for the enhanced awakening probability are discussed.

Noise Abatement Trajectory Optimization using Genetic Algorithms
TL;DR: A technique is presented to minimize the noise nuisance by optimizing the trajectory of the aircraft for a single event by segmenting it in such a way that it is only consisted of a series of straight-line segments which are connected by fly-by waypoints.

Night-Time Noise Index Based on the Integration of Awakening Potential.
TL;DR: A night-time noise index, Nawake,year, was redefined based on the integration of the awakening potential unit estimated from the existing dose-response relationships of awakening, which considers the total number of awakenings and covers a wide-range and number of noise events.
