Occupational noise in urban buses

International Journal of Industrial Ergonomics, 2006
Abstract The noise level environment for Brazilian urban bus drivers (city of Curitiba) was examined. Noise levels were measured in 3 types of buses: (1) bi-articulated, (2) speedy, and (3) feeder, 20 buses of each type. Bi-articulated buses are formed by three cars and two hinges, and operate in exclusive lanes, where cars are not allowed. They stop

Occupational noise exposure and blood pressure

Journal of Hypertension, 1994
To investigate the relationship between occupational noise exposure and blood pressure.We studied 8811 workers at a metallurgical factory, who were exposed to different levels of noise at the worksite: < or = 80 dB for 8078 workers and > 80 dB for 733 workers. A clinical examination, including measurements of blood pressure (by mercury sphygmomanometer,

Occupational noise and demographic factors in hearing

Acta Oto-Laryngologica, 1991
The effects of age, sex, socioeconomic background and noise exposure on hearing were examined in a population sample. Subjects, aged between 17 and 80 years, were selected from the electoral register using a stratified random sampling technique based on age and reported hearing difficulty.

Statistical evaluation of occupational noise exposure

Applied Acoustics, 2005
Abstract Assessment of the risk involved in occupational noise exposure ( L EP,d ) is significantly affected by assumptions and uncertainties in setting true exposure conditions meaning that the calculation according to the European legislation might not be fully representative.

No-occupational exposure to noise.

Giornale italiano di medicina del lavoro ed ergonomia, 2005
The aim of the research was to evaluate the risk for the health of the disco-goers related to no-professional exposition to noise produced by speakers of discos. The noise has been measured in the middle of a disco using a class 1 phonometer. The exposition level was calculated using the formula quoted in the D.Lgs 277/91 (Italian legislative decree ...

Occupational noise exposure and hearing levels

American Industrial Hygiene Association Journal, 1981
A study was made at the Bhabha Atomic Research Center to measure the hearing levels of persons working in a noisy environment. Two different workplaces, central air-conditioning plant and glass flowing shops, where a number of persons were exposed to noise levels exceeding 85 dB(A) were chosen.

Occupational noise levels in orthopaedic surgery

Irish Journal of Medical Science, 1999
Prolonged exposure to potentially damaging noise levels in the workplace has been the subject of much recent litigation. The occupational risk of noise induced hearing loss among orthopaedic surgeons is unknown. Continuous readings of air-powered instruments routinely used in orthopaedic surgery were made in a regional trauma unit at standard distance ...

Noise and Occupational Medicine

Journal of Occupational & Environmental Medicine, 2019
: Noise-induced hearing loss (NIHL) represents the second most common occupational disease in the United States. Although the Occupational Safety and Health Administration (OSHA) has promulgated an occupational noise exposure standard and associated recordkeeping requirements, OSHA inspections increasingly document practices that violate both the noise

Occupational Noise — The Unavoidable Health Hazard

Journal of the Royal Society of Health, 1985
threat to physical and psychological well-being, the sounds of our technology follow us through our working, leisure, and sleeping hours. Noise sources are multiplying rapidly. The industrial and technological development of urban society is producing an increasing number of devices with higher noise outputs.

Occupational Noise Exposure of Operators of Heavy Trucks

American Industrial Hygiene Association Journal, 1998
Over 400 measurements were taken across Canada to assess the noise exposure of truck operators. The exposure of the driver was evaluated using both 3-dB (Leq) and 5-dB (L5dB) exchange rates. Driving with windows closed and radio not operating resulted in the lowest exposure.
