Assessment of Traffic Noise Pollution due to Road Traffic

Advances in Science and Technology, 2021
The paper presents aspects related to noise pollution due to road traffic in Drobeta Turnu Severin. The main noise sources in Drobeta Turnu Severin are: road transport, railway and industrial activities. Based on the noise level measurement performed to assess the traffic noise over a period of 7 years, namely between 2013 and 2019, on an important ...

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 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.

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.

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 ...

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.

Variations of road traffic noise in residential areas

The Journal of the Acoustical Society of America, 2008
The ability to predict road noise in urban area is important. The community noise equivalent level (Lden) varies from day to day (weekdays, weekends, holidays, etc.). There is a need to compromise between the accuracy in the determination of Lden and limited resources of input data, the measuring equipment, and time.

Road traffic noise and cardiovascular disease

International Archives of Occupational and Environmental Health, 1979
In a population study, an attempt was made to answer the question whether people living in a street with much traffic (noise) run an increased risk of contracting cardiovascular diseases.

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

Road traffic noise and disturbance to sleep

Journal of Sound and Vibration, 1977
Abstract 2933 respondents resident at 53 sites in Greater London were interviewed to obtain data with respect to sleep disturbance. The questionnaire employed covered health and sleep experience, actions taken to ensure sleep, believed causes of disturbance, and procedures aimed at reducing noise within the bedroom.
