• HLSim - NIOSH Hearing Loss Simulator
  6/8/2022 - PC software
  Use this training and communication tool to demonstrate the effects of noise exposure on hearing.
• What Does a Hearing Loss Sound Like?
  9/19/2012 - Training materials
  Loud noise can permanently damage your hearing. It especially affects the sounds that help you understand speech. To hear what this sounds like, try these computer-generated samples.
• 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.
• Mine Hearing and Communication Safety System
  6/13/2023 - Contracts and cooperative agreements
  Triton Systems proposes to develop a new product—“MineEar”—which would offer superior awareness, communication, and hearing protection through noise attenuation, occlusion effect reduction technology, and advanced noise reduction.
• The Evolution of Drill Bit and Chuck Isolators to Reduce Roof Bolting Machine Drilling Noise
  1/1/2012 - Peer reviewed journal articles
  This paper documents the evolution of the bit isolator and chuck isolator. Laboratory testing confirms that production bit and chuck isolators reduce the A-weighted sound level generated during drilling by 3.7 to 6.6 dB.
• Analysis of a Mechanism Suspension to Reduce Noise from Horizontal Vibrating Screens
  11/1/2011 - Peer reviewed journal articles
  The National Institute for Occupational Safety and Health (NIOSH) is developing noise controls to reduce noise generated by horizontal vibrating screens.
• Noise Controls for Vibrating Screen Mechanisms
  1/1/2011 - Peer reviewed journal articles
  NIOSH is currently developing noise controls for horizontal vibrating screens.
• Evaluation of Stiffeners for Reducing Noise from Horizontal Vibrating Screens
  4/1/2010 - Conference papers
  NIOSH is developing noise controls to reduce noise generated by horizontal vibrating screens. This paper documents testing of the stiffeners.
• Less Sound Underground: Reducing Roof Bolting Machine Drilling Noise
  4/1/2010 - Conference papers
  This article presents the most significant findings from NIOSH research to develop noise controls that reduce the sound at the operator’s position of mining machinery.
• Development of Roof-Bolting Machine Bit and Chuck Isolators for Drilling Noise Reductions
  11/1/2009 - Conference papers
  NIOSH is developing bit and chuck isolators to reduce vibration, and thus noise radiation of the drill steel, with the longer-term goal of reducing roof bolting machine operator noise exposure.
