BACKGROUND Residential traffic noise exposure may entail sleep disruption and compromised circadian functioning; two factors which have been associated with a poor colorectal cancer (CRC) prognosis. Hence, the aim of the present study was to investigate the association between residential road traffic noise and CRC survival. METHODS AND MATERIALS Road traffic noise was calculated for all resi...

The objective of the study is to develop GIS based noise simulation software for heterogeneous traffic conditions in metropolitan cities. In the present study traffic noise simulation software has been developed for sound level calculation. The software covers the following five input variables i.e., noise sources (point and mobile), vehicle speed, distance, honking and noise attenuation while ...

Transportation noise contains significant low frequency components. It is difficult to sound insulate buildings against transportation noise because wall cavities are only effective in increasing sound insulation above the mass-air-mass resonance frequency. Stud walls can also have a significant structural resonance in this low frequency range, although it is not yet clear if this is significan...

Traffic accidents are more frequent for sleep apnea syndrome (SAS) patients than in the population at large. The mechanisms that underlie this observation are poorly defined. Our working hypothesis was that in SAS patients the steady noise of a car engine might alter cognitive capacities that may be involved in driving, thus increasing the risk of traffic accidents. To test this hypothesis we d...

background: more than 20% of deaths from traffic crashes are related to pedestrians. this figure in tehran, the capital of iran, reaches to 40%. this study aimed to determine the high-risk areas and spatially analyze the traffic crashes, causing death to pedestrians in tehran.   methods: mapping was used to display the distribution of the crashes. determining the distribution pattern of crashes...

Even for same LAeq, noise immissions from different types of traffic noise elicit not always the same loudness and annoyance. Frequently, railway noise is perceived as less annoying than road traffic noise (railway bonus), whereas aircraft noise can be perceived as more annoying than road traffic noise (aircraft malus). As one possible reason for the aircraft malus in addition to differences in...

OBJECTIVES Published reports suggest that some adverse health impact may be related to noise exposure, and motor vehicle traffic is considered to be the main source of environmental hazard of noise. The aim of this study has been to assess an association between occurrence of sleep and attention disorders with exposure to the noise generated by motor vehicle traffic in the case of a large group...

BACKGROUND Traffic noise has been associated with prevalence of hypertension, but reports are inconsistent for blood pressure (BP). To ascertain noise effects and to disentangle them from those suspected to be from traffic-related air pollution, it may be essential to estimate people's noise exposure indoors in bedrooms. OBJECTIVES We analyzed associations between long-term exposure to indoor...
