Are the risks of NIHL specific to certain occupations, such as mining?

Noise-Induced Hearing Loss (NIHL) is an across-the-board risk in all industries - including mining.

Answer Extra: 

In one study, approximately 40% of noise survey samples taken for longwall occupations exceeded the Permissible Exposure Level (PEL) of 100%. Noise doses up to 786% for longwall coal mining system workers were sampled in such job classifications as shearer operator, jacksetter (shieldman), longwall foreman, and headgate (stageloader) operator(1). 

Another study found that 69% of the noise exposure of sand and gravel miners at surface and nine dredge operations was over the 85 dBA REL. The same survey reported that 48% of these miners never used hearing protectors(2),
