Noise-induced hearing loss continues to be a problem in the well drilling industry. Research conducted by NIOSH found that air rotary drill rigs produce sound levels more than 90 dB(A) over the course of an eight-hour workday. Sounds levels above 90 dB(A), identified during hammer drilling and the hammering of casing, exposes workers to levels that can damage hearing. A typical air rotary drill rig provides no barrier, for noise and dust protection, between the drill’s control panel and the drill stem.
