TL;DR: In this article, the present situation in China regarding railway environmental noise is given in this paper, where emission standards and methods of measurement of railway noise on the boundary alongside the railway line (GB12525-90) are introduced, followed by typical noise levels and spectra alongside main railway lines and the noise propagation pattern with distance (which have been monitored over decades).

TL;DR: In this paper, the authors investigated typical noise reductions for residences near wind farms that are located in rural areas in Australia and found that during the night, when the wind farm is operating and the local wind speed is low, the A-weighted outdoor to indoor noise reductions with closed windows are less than 20dB, which is at least 10dB lower than the value generally assumed for traffic noise in urban areas.

TL;DR: In this article, the authors examined the impact on life satisfaction of self-perceived levels of air and noise pollution in the workplace and provided a monetary valuation of these environmental conditions, using the life-satisfaction approach.

TL;DR: In this article, the authors present an overview of recent urban projects and policies that deal with noise control and how these experiences will match into the next years with the sound characteristics of new electric vehicles for private and public transportation.
Abstract: Limited Traffic Zone (LTZ) is a planning strategy that is more and more adopted by municipalities in Europe to improve their environmental conditions. It consists in the prohibition for traditional vehicles to circulate in specific areas. Although the main aim is to tackle air pollution problems, positive effects are registered in terms of reduction of noise annoyance and in terms of improved “quality of life” if specific conditions are respected. On the other side under the drive of the global market, the number of circulating electric vehicles in urban sites is also increasing. In the next years we expect to experience a new and not well-known urban soundscape.
In this paper is presented an overview of recent urban projects and policies that deal with noise control and how these experiences will match into the next years with the sound characteristics of new electric vehicles for private and public transportation.

TL;DR: Changes in present USA noise-measurement procedures and noise-control guidelines are proposed that provide more accurate predictions of annoyance, related adverse effects, and criteria for setting "tolerable" limits of noise exposure in residential areas.
Abstract: A demonstration field-research study reveals that aircraft noise measured at two one-story houses is ∼9dB less attenuated from measured outdoor levels than is street traffic noise, and, found in other studies, ∼14dB less than railway noise. Comparable differences are found between these noises from the application of basic acoustical formulas for quantifying attenuations that occur on site of one- and two-story houses. Reasonably consistent with those findings are results from attitude surveys showing that daily exposure levels of aircraft must be ∼8dB less than levels of street traffic noise, and ∼13dB less than levels of railway noise to be perceived as an equal cause of annoyance and related adverse effects. However, USA government guidelines recommend that equal exposure levels of noise measured outdoors from vehicles of transportation should be considered as being equally annoying. Changes in present USA noise-measurement procedures and noise-control guidelines are proposed that provide more accurate...
