Air Absorption Of Traffic Noise
Journal of Sound and Vibration, 1993Air absorption is considered as a phenomenon modifying geometrical spreading. Expressions for the maximal A-weighted sound pressure level and the A-weighted sound exposure level are derived for train noise. They are given in terms of the tabulated change in sound pressure level due to air absorption for particular values of characteristic frequency ...

The Journal of the Acoustical Society of America, 1997
A one-parameter model (ξ) for stop-and-go noise is developed. The physics of the phenomenon is based on the idea of the linear density of radiated energy. The methodology of ξ determination has been worked out and illustrated. The noise interaction with the surface of the ground is considered to be the only wave phenomenon that disturbs geometrical ...

The effects of various traffic, ground cover, and geometric conditions on traffic noise propagation were evaluated in this study. There were two general methods of data collection. The first method consisted of using as many as four sound-level meters and graphic-level recorders to take simultaneous recordings of the traffic stream; the second method ...

Hypertension and Road Traffic Noise Exposure
Journal of Occupational & Environmental Medicine, 2007The purpose of this study was to assess the relationship between road traffic noise exposure at home and the prevalence of hypertension.We conducted cross-sectional analyses in a large random sample (N=40,856) of inhabitants of Groningen City, and in a subsample (the Prevention of Renal and Vascular End-Stage Disease [PREVEND]) study cohort; N=8592 ...

Applied Acoustics, 1970
Traffic noise needs to be described in physical terms such that measurements or predictions of noise exposure in these units are effectively measurements or predictions of nuisance. Such units are developed by the means of social surveys, and typical survey techniques are briefly described.

Describes a socio‐psychological study performed in a residential area of Tehran, exposed to both aircraft and traffic noise. Analysis of residents′ responses to road traffic noise shows that although aircraft noise is the chief environmental problem it fails to mask the nuisance of traffic noise.

Reviews of Physics in Technology, 1972
Following the publication of the Wilson report in 1963 much attention has been drawn to solving problems connected with road traffic noise. In this article the relevant noise level standards are described and the phenomenon of noise from individual vehicles and taffic as a whole is discussed.

In the field of transportation research it is of interest to calculate the noise-producing properties of a stream of equidistant acoustic sources moving at constant speed. Weiss (1970) developed a probabilistic model of traffic noise intensity from vehicles on a long straight highway.
