Ideally noise measurements have been taken of operating equipment and documented. If this has not occurred yet, a table has been provided on the back of this resource, providing examples of noise levels of various mining equipment. It is recommended that

Noise in Construction | EHS Today

For example, a shop floor, which has production equipment and operates on a daily basis, has noise levels that generally do not change unless something in the production area changes. Such changes can range from the addition of equipment, to the changing of the materials being processed and produced, to machine malfunctions and changing of the workspace, such as the addition or removal of walls.

Noise Pollution and Its Control in Mining

The most noise generating equipment underground are the haulage, ventilators-main, auxiliary and forcing fans, conveyor transfer points, cutting and drilling machines. The ambient noise level due to different operations in underground mines varies within 80-104 dBA.

Appendix Appendix Appendix J

The main noise sources are expected to be from mine plant and equipment (excavators, haul trucks, dozers, graders etc.), the processing plant (crushers, ball mills and conveyors and drives etc.) and the power station (gas engines etc.).

Noise in motor vehicle repair

Noise levels from panel beating and other repair operations using hand tools are variable but generally high; noise from work with sheet metal is often around 93 dB(A). Welding and flamecutting can also be noisy, and paint spraying has been measured at 93 dB(A).

Noise

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; 1,000 impulses at 130 dB; 100 impulses at 140 dB ...
