Long-term noise exposures: A brief review
Occupational regulations are developed to conserve the hearing of a worker noise-exposed for 8 h per day. Workers often work longer shifts. In order to account for longer exposures, regulators have adopted variations of the equal energy hypothesis in which the ear is modeled as an integrator of acoustic energy over time. Thus time and energy can be traded to produce equal hearing loss. This res...
متن کاملInvestigation of job stress among urban bus drivers with respect to daily noise and vibration exposures
Background and Objectives: Bus drivers are exposed to harmful agents such as noise and vibration which may led to increasing the level of job stress among them. The aim of this study was to evaluation of job stress among urban bus drivers with respect to daily noise and vibration exposures. Methods: This cross-sectional study carried out with participation of 103 urban bus drivers in Hamadan, ...
متن کاملTask-based noise exposures for farmers involved in grain production.
Few studies have been done examining noise exposures associated with agricultural tasks. This study was conducted to address that research gap by calculating the noise exposures for tasks and equipment associated with grain production and assessing the variability in those exposures. An additional aim of this study was to identify tasks and equipment that could be targeted for intervention stra...
متن کاملEvaluation of potential noise exposures in hospital operating rooms.
The National Institute for Occupational Safety and Health received a health hazard evaluation request from West Virginia University Hospital, Morgantown, to evaluate noise exposures from surgical instruments in the OR. Four surgical technologists, four RNs, and one surgeon wore noise dosimeters to measure full-shift personal noise exposures during two days while they performed typical daily act...
متن کاملNoise Characterization of Weighting Schemes for Combination of Multiple Exposures
A method for capturing high intensity dynamic range scenes with a low dynamic range camera consists in taking a series of images with di erent exposure settings and combining these into a single high dynamic range image. The combined image values are found by weighted averaging of values from the di erently exposed images on a per-pixel basis. This paper reviews existing weighting schemes and c...
