Paper in Inter-noise 89 Inst Noise Control Eng Poughkeepsie NY :1021-1024
Percussion drills used in mining and quarrying operations pose one of the greatest dangers to the hearing of the people employed in those industries. Drilling holes in rock for blasting or ground support purposes is an energy-intensive process that requires a rugged and powerful machine that is inherently noisy. This paper describes a U.S. Bureau of Mines research program to investigate the noise-generating mechanisms of rock drills as part of its overall noise research effort.
