• Description:
  Percussion-type rock drills are commonly used in both coal and metal-nonmetal mines; they produce extremely high noise levels (110 to 120 dBA) and have complex noise-generating mechanisms. Therefore, engineering noise controls for percussion drills have been very difficult to achieve. However, substantial progress has been made toward this goal through the use of retrofit techniques and percussion drill redesign. This paper provides an overview of Bureau-sponsored research programs aimed at reducing the noise produced by percussion drills. [Description provided by NIOSH]
