Road traffic noise affects a large number of people, especially in urban areas and is generally a major source of complaints. This paper refers to a study of the problem of traffic noise on roads which have been transformed into streets in the city of Erzurum. Noise levels are measured and the impacts suffered by the community are documented. Manual noise measurements were made along 12 streets...
The present study provides an evaluation of road traffic noise pollution in the city of Amman and its effects on residents. Statistical noise index L10(18 hr) was measured at nine different sites throughout the city of Amman. The British Calculation of Road Traffic Noise (CRTN) method was used to predict noise levels at the chosen sites. The CRTN method proved to be successful in predicting noi...
BACKGROUND An increasing number of children are exposed to road traffic noise levels that may lead to adverse effects on health and daily functioning. Childhood is a period of intense growth and brain maturation, and children may therefore be especially vulnerable to road traffic noise. The objective of the present study was to examine whether road traffic noise was associated with reported ina...
Traffic noise is an established risk factor for some cardiovascular diseases such as hypertension and ischaemic heart disease, but the evidence regarding stroke is still limited. In this study we aimed to systematically review the related epidemiological data and make a meta-analysis of the risk of stroke morbidity associated with road and air traffic noise exposure. We searched articles in Eng...
This paper presents the noise pollution status of Rohtak city with emphasis on objective day night noise measurement and subjective response of people. Twenty different sites were selected to measure the noise level and determine noise sources at these selected sites. Selected sites fall in the category of residential, commercial, silence zone and road traffic junctions. Noise level measurement...
BACKGROUND Few modifiable risk factors for prostate cancer are known. Recently, disruption of the circadian system has been proposed to affect risk, as it entails an inhibited melatonin production, and melatonin has demonstrated beneficial effects on cancer inhibition. This suggests a potential role of traffic noise in prostate cancer. METHODS Road traffic and railway noise was calculated for...
Traffic Density Estimation and Mechanical Condition Determination of Vehicles using Acoustic Signals
In this paper we will estimate the vehicular traffic density by using cummulative acoustic or sound signals. Here we will estimate three probable conditions of traffic that is heavy flow traffic (0-10km/h), medium flow (2040km/h), and free flow (above 40km/h) traffic. Cumulative sound signals consist of various noise signals coming from various parts of vehicles which includes rotational parts,...
