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 ...

Summary. Noise is any unwanted sound that has the potential to interfere with communication and to damage people's hearing. Noise Induced Hearing Loss (NIHL) is a permanent impairment of hearing, resulting from exposure to excessive noise. NIHL is one of the most prevalent occupational injuries in the South African mining industry.

A holistic view of the entire noise control science has three primary dimensions: (1) the noise source, (2) the process of noise propagation (transmission) and (3) the effect (response) of noise to the receiver. First-level noise control applies to the source in terms of noise engineering to reduce and eliminate noise.

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).
