Abstract: Noise, which is composed of unwanted sound, is a significant source of environmental pollution. When. levels of noise exposed in the various branches of i ndustry are analyzed, mining ...

Previous studies and research efforts have shown that noise-induced hearing loss (NIHL) is a problem in the U.S. mining industry. In response, researchers at the National Institute for Occupational Safety and Health (NIOSH) have been conducting a cross-sectional survey of equipment noise and worker noise exposures in the mining …

Unfortunately, noise and hearing loss are still a problem for today's miners. Mining has the highest prevalence of hazardous noise exposure of any major industry sector (Tak, Davis, and Calvert 2009) and mining is second only to the railroad industry in prevalence of workers reporting hearing difficulty (Tak and Calvert 2008). Noise-induced

In the mining industry, noise pollution is not a new concept. The mining community has the highest and persistent hazardous level of noise exposure to which workers are exposed when compared with other industries. ... This is due to various noise sources in mines, e.g., excavators, dumpers, dozers, loaders, drilling machines, …

The management of noise from mining operations is a fundamental responsibility of mine operators. Noise level monitoring is one method used to assess the potential for hearing loss among workers and to determine whether noise mitigation measures are effective. Solutions such as sound attenuation can allow for extended operating hours, increased ...

See Answer. Question: Mining is inherently a noisy trade and there is forever a risk that people might be exposed to excessive noise that could impact on their health. Critically investigate the issue of noise in industry in general and mining in particular and submit a comprehensive report. You should at the very least report on the following ...

Purpose: The purpose of this programmatic area is to build a database that contains up-to-date comprehensive proiles of the noise exposures to the mining population as a …

The mining industry plays a crucial role in the global economy. Mines are currently one of the two sources that provide almost all of the raw materials used throughout the world [ 1 ].

A crosssectional survey of noise sources and worker noise exposures in the mining industry to address a knowledge gap and characterize noise sources sufficiently well so that the sources most hazardous to hearing are identified and those conditions of exposure that are most amenable to engineering controls are pinpointed ar. Prolonged exposure to …

The results indicate that the mean noise expo sure levels in the South African mining industry range f rom 63.9 dBA t o 113.5 dBA and t hat approximately 73.2 per cent of miners in the

Studying the noise sources in the mining industry shows that workplaces are dominated by medium and high frequency noise, which is 85–100 dB and often reaches 110–120 dB [1]. The development of pathology in workers is most typical for exposure to sound in the high frequency range (from 3000 to 6000 Hz).

els encountered in the open cast mining industry are sec-ond only to that encountered near jet engines at airports [3]. Noise-induced hearing loss usually occurs initially at high frequencies (3k, 4k, or 6k hz), and then spreads to the low frequencies (0.5k, 1k, or 2k hz) [4]. Sources of Noise noise, defined as undesirable sound, is a by-product

Noise pollution in the surrounding mining areas or construction sites within variety of equipment causes by several sources of noise such as processing plants [16], blasting and machinery [17 ...
