The mining industry is a source of international economic activity, with revenues of over 500 billion USD. It requires minute precision to move tons of rocks on machines, and any mistake in the finely tuned process can lead to major consequences in the mining operations.

There are many risks facing those who work in the mining industry. Not necessarily the least of these being hearing loss. Working constantly next to heavy, loud equipment like conveying systems, drills, and other machinery should be enough to motivate mine workers to wear hearing-protective gear. But, many workers do not, and subsequently suffer some form of hearing loss.

Workplace hearing protection programs typically focus on individuals with normal hearing. But what about workers who already suffer from some level of hearing loss?  Even in quiet environments, workers with hearing loss face a number of challenges, including difficulty communicating with colleagues and problems with differentiating important sounds above background noises.

There’s no question that the mining industry is filled with high-noise environments that require hearing protection devices (HPDs) in order for workers to perform safely. But when traditional HPDs interfere with worker communication, the devices are often removed so that workers can talk to one another, exposing them to the risk of hearing loss the HPDs were intended to prevent. 

This risk may be best summed up by the CDC, which features a paper on its website from the Noise Control Engineering Journal that states:

"[M]iners frequently complain of reduced audibility or confusion about identifying spoken words when wearing conventional hearing protectors. This leads to an increased risk of miners being struck by moving equipment or errors in communication with co-workers. Miners will often remove their hearing protectors to overcome these obstacles.”

"Exposure to silica can be deadly, and limiting that exposure is essential. Every year, many exposed workers not only lose their ability to work, but also to breathe. This proposal is expected to prevent thousands of deaths from silicosis – an incurable and progressive disease – as well as lung cancer, other respiratory diseases, and kidney disease. Workers affected by silica are fathers, mothers, sisters and brothers lost to entirely preventable illnesses. We're looking forward to public comment on the proposal."
