Traffic Noise

International Journal of Artificial Life Research, 2011
In this paper, the study of traffic noise is presented from the point of view of 1/f noise. Samples of Traffic Noise are collected from selected locations from busy roads of Aurangabad city in Maharashtra state (India) and data is analyzed. It is observed that in many cases the traffic noise possesses pink noise (1/f noise) prevailing over appreciable ...

Noise quality of traffic noise

The Journal of the Acoustical Society of America, 2007
Traffic noise is considered as one major source of noise annoyance in urban context indicated by the increasing number of complaints. The neglect of quality parameters regarding pass-by noise appears as a basic cause for the unreduced annoyance. Several parameters besides the SPL have an important influence on noise evaluation, such as low frequency ...

IS FREIGHT TRAFFIC NOISE MORE ANNOYING THAN PASSENGER TRAFFIC NOISE?

Journal of Sound and Vibration, 1996
In the Netherlands a new freight-only railway route, the "Betuweroute", is being planned to carry freight traffic from Rotterdam harbour east into Germany. Inhabitants of areas near the future route are concerned about noise and vibration, and question the relevance of current legislation for a "freight-only" line.

Health effects of traffic noise

International Archives of Occupational and Environmental Health, 1980
In 57 test persons having worked 1 day under traffic noise (Leq = 85 dB(A) and 1 day without noise (Leq < 50 dB(A), blood pressure and pulse frequency were measured at 1 h intervals and total urine was collected during working hours. Additionally, blood was sampled at the end of each working day.

Traffic and noise in children's wards

Medical Journal of Australia, 1994
To measure pedestrian traffic volumes and noise levels in paediatric open bay areas and discuss their impact on the care of sick children.Between August and October 1992, we recorded the number and duration of entrances to two open bay areas comprising eight and ten beds respectively in a ward for infants and a ward for older children.

Traffic noise and traffic light control

Transportation Research Part D: Transport and Environment, 1998
Abstract An optimal control problem of traffic light duration is considered. The traffic noise level is introduced as a state variable in a dynamical optimization problem. A closed loop control system is designed which influences the green duration of the lights according to the equivalent noise level.

Hypertension and Road Traffic Noise Exposure

Journal of Occupational & Environmental Medicine, 2007
The 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 ...

Investigations of Effects of Porous Pavement on Traffic Noise and Traffic Noise Prediction

Transportation Research Record: Journal of the Transportation Research Board, 2013
The U.S. Department of Transportation's FHWA Traffic Noise Model (TNM) is currently missing the effect of sound-absorbing pavements on predicted noise levels, in regard to both a reduction in source level and a reduction of sound through propagation.
