Despite there being nearly 30 years of hazardous occupational noise regulation within the mining industry, noise-induced hearing loss still remains an issue. A whopping 80% of American miners work in an environment where the time-weighted average (TWA) noise levels exceed 85 dB(A). Moreover, 25% of these miners are exposed to TWA noise levels ...

Addressing Mining Noise. Mining is an industry based on the extraction of geological materials from the earth. As such, it requires powerful, heavy machinery and destructive techniques, both inevitably generating intense mining noise if not mitigated by noise control. Machines such as pneumatic and percussion tools are a major source of mining ...

A lack of understanding and insufficient processes to managing noise in mining can lead to significant operating losses. The most common is a limitation to operating hours with some mines only able to operate during certain hours and even weather conditions which ensure sound output is reduced.. Understanding mining noise gives operators the ability to fully optimise their plant …

In contrast, only 10% of the population that experienced non-occupational exposure to noise had any hearing loss by the age of 50 (Rider, 1999). Despite more than 30 years of regulation within the mining industry, 76% of miners are still exposed to hazardous levels of noise.

Mining is one of the most dangerous jobs in America, with cave-ins and explosions just some dangers miners face daily. Yet noise from mining has been reported as an under-represented issue that lasts for long periods without interruption – though studies show anything over 85 dB can be harmful depending on factors such as frequency or length of exposure to it.
