Adverse noise effects generated by a facility can be avoided or reduced at the point of generation thereby diminishing the effects of the noise at the point of reception. This guidance identifies various mitigation techniques and their proper application either at the source of noise generation or on a facility's ...
Evaluation of the effects of occupational noise exposure ...
The existing literature indicates that occupational exposure to noise may have adverse effects on workers' health. The aim of this study was to evaluate the possible effects of exposure to different sound pressure levels (SPLs) on serum aldosterone and potassium concentration among Iranian blue collar workers in Golgohar Mining and Industrial Company in Sirjan, Kerman Province, Iran.noise levels at a mining facility maltanoise levels at a mining facility malta.

It is important to differentiate between noise level and time-weighted average noise exposure. While noise levels describe the intensity of sounds at a given point in time, the NIOSH and EPA exposure limits are set as time-weighted average exposures over periods of time.
Noise - Occupational Exposure Limits in Canada : OSH Answers
Noise regulations in several jurisdictions treat impulse noise separately from continuous noise. A common approach is to limit the number of impulses at a given peak pressure over a workday. The exact figures vary slightly, but generally the regulations in which the exchange rate is 5 dB permit 10,000 impulses at a peak pressure level of 120 dB ...Noise Pollution and Its Control in MiningSound Level: Noise known as a major health hazard is spot specific in case of underground mining where the operators are exposed to continuous background noise while high level short duration noise peaks are common in case of surface mining. The human ear is most sensitive in 2 to 5 KHz range and less sensitive in high and low frequencies.Applications of Noise Control in the Mining Industry ...Jan 08, 2015· The most critical areas for attention regarding hazardous mining noise include the face areas of underground coal mines (43% of workers were shown to experience noise exposures above permissible levels) and coal preparation plants (over 53%; et al., 2006).
