9 Review of Noise-Induced Hearing Loss Prevention Research .

Engineering measurements show that the sound power levels of roof bolters and continuous mining machines have been reduced, which in turn has resulted in reduced noise levels (and exposures) at the operator position (NIOSH, 2005a). Unlike long-term exposure and audiometric records, laboratory data are objective.
