• Technology News 548 - Bit Isolator Reduces Drilling Noise in Underground Coal Mines
  3/1/2012 - Technology News
  This paper describes an engineering noise control that reduces roof bolting machine (RBM) operators’ exposure to noise in underground coal mines, thereby decreasing the risk of noise-induced hearing loss (NIHL) in RBM operators and nearby workers.
• Hearing Loss in the Mining Industry: The Evolution of NIOSH and Bureau of Mines Hearing Loss Research
  1/1/2010 - Book chapters
  The NIOSH strategy expands on decades of research by its U.S. Bureau of Mines predecessors that identified some of the key issues with underground and surface noise sources.
• Noise Control in Underground Metal Mining
  12/1/2009 - Information Circulars
  This document describes principles of noise control to operators, safety personnel, and mechanics in the mining industry so that they can evaluate the extent of a noise problem, determine the best approach, and apply the most appropriate solution.
• Technology News 531 - Engineering Controls for Reducing Continuous Mining Machine Noise
  9/1/2008 - Technology News
