Road 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.

Road traffic noise annoyance in Amsterdam

International Archives of Occupational and Environmental Health, 1985
3445 persons living in Amsterdam (1507 male and 1938 female), aged 41-43 years, participated in an investigation in which the relationship was studied between the (measured) road traffic noise in front of the houses in which the participants lived, and the (reported) resulting annoyance and sleep disturbance.

Road traffic noise, noise sensitivity and psychological disorder

Psychological Medicine, 1993
SynopsisThe relationship between traffic noise exposure and psychological morbidity was assessed using the population-based Caerphilly Collaborative Survey of 2398 men from Caerphilly, South Wales. The findings showed that traffic noise exposure levels were strongly associated with annoyance to noise.

ROAD TRAFFIC NOISE INFLUENCED BY ROAD BUMPS

Journal of Sound and Vibration, 2002
Noise levels from different kinds of vehicles were measured on streets close to road bumps. In comparison with free flowing traffic, the acceleration after road bumps increased peak noise levels from 1 to 13 dB (A) max. Although the results are of a pilot nature, it is suggested that noise consequences should be included in the planning of road bumps.

Road traffic noise, sleep and mental health

Environmental Research, 2014
This study examines the relationship between road traffic noise, self-reported sleep quality and mental health. The study is cross-sectional and based on data from a survey conducted in Oslo, Norway, in 2000. Psychological distress (Hopkins Symptom Checklist, HSCL-25) was measured along with self-reported somatic health, sleep quality, noise ...

Maximum noise levels in road traffic noise

Journal of Sound and Vibration, 1988
Certain field investigations have shown that the correlation between the extent of annoyance due to road traffic noise and the noise dose expressed in leq is rather poor. A higher correlation was found when the expression of the noise dose was based upon the maximum noise level (mnl) from the single noisiest event. To determine the relation between leq

Noise from complex road traffic

Journal of Sound and Vibration, 1971
The noise from freely flowing traffic is calculated considering traffic mixes, numerous roads, barriers, and other influences that can be approximated by the superposition of contributions from statistically independent elements. The basic statistical parameters derived are the cumulants of the intensity distribution.

Road traffic detection using wireless noise sensors

2012 IEEE International Conference on Communications (ICC), 2012
In this paper we present our experimental result of using wireless noise sensor network (WNSN) to detect road traffic. With the features implemented in our network such as multipoint measuring, synchronization, real-time data availability, and strict compliance of sound level meter (SLM) standard IEC 61672:2003, we assert the possibility of using WNSN ...

Statistics of road traffic noise

Journal of Sound and Vibration, 1971
Abstract Freely flowing traffic is modeled by randomly distributed sources on a line. Statistical parameters of the noise emitted from point sources of equal strength are derived in terms of the cumulants of the intensity normalized by its mean.

Prediction of Road Traffic Noise

The Journal of the Acoustical Society of America, 1972
A computer model for the prediction of noise from freely flowing road traffice is described. The model allows one to account for simple statistics of point sources (spatial distribution and radiated sound power) and for sound propagation with attenuation, diffraction, and reflection.
