Energy Reports, 2020 Urban noise depends on several factors from which Traffic Noise is the most important. City centers and main access roads are usually over exposed that is, average day–evening–night noise level [LDEN] and/or rest expose level [LNIGHT] surpasses a ...

Road traffic noise and hypertension [PDF]
Occupational and Environmental Medicine, 2006 Background:It has been suggested that noise exposure increases the risk of hypertension. Road traffic is the dominant source of community noise exposure.Objective:To study the association between exposure to residential road traffic noise and hypertension in an urban municipality.Methods:The study population comprised randomly selected subjects aged 19–

, 2021 Currently, noise pollution is a major problem especially in urban areas, and moreover traffic noise is the most significant source of noise in cities. A large number of cars and other road vehicles that have internal combustion engines are making road traffic noise a leading noise pollution source.

Atmosphere, 2022 Road traffic simultaneously emits noise and air pollution. This relation is primarily assessed by comparing A-weighted noise levels (LAeq) and various air pollutants.

Traffic noise and the hyperbolic plane [PDF]
Annals of Physics, 2010 We consider the problem of sound propagation in a wind. We note that the rays, as in the absence of a wind, are given by Fermat's principle and show how to map them to the trajectories of a charged particle moving in a magnetic field on a curved space. For the specific case of sound propagating in a stratified atmosphere with a small wind speed we show

Traffic Noise and its Impact on Wellness of the Residents in Sambalpur City – a Critical Analysis
Archives of Acoustics, 2021 Noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing. Like air pollution, noise pollution is one of the serious matters of concern in urban areas. Noise pollution occurs when noise level exceeds certain limit and has deleterious

Evaluation of Strategic Noise Maps Arising from Urban Traffic
Doğal Afetler ve Çevre Dergisi, 2021 Environmental noise from traffic, industry and entertainment in cities has been one of the important environmental problems. In developed countries, noise from highways, airways and railways are the second major health problem. Traffic noise has negative

INTERDEPENDENCE OF NOISE AND TRAFFIC FLOW [PDF]
TRANSPORT, 2008 Traffic flows in cities, especially in city centres, are intensive and uneven, moreover, registered noise levels exceed allowable limits. Noise levels have been measured at K. Mindaugo ave. and Birštono street crossing in Kaunas and data of automated traffic flow registration equipment have been used.

Dynamic estimation of urban traffic noise: Influence of traffic and noise source representations [PDF]
Applied Acoustics, 2008 The need for traffic noise prediction models that take traffic dynamics into account has been recently shown for urban areas. Such models couple a dynamic representation of traffic with noise emission laws. The contribution of the paper is to test different traffic and noise source representations for LAeq and statistical levels estimation.
