• Noise Reduction of Continuous Miner Scrubber Fan System
  2/1/2018 - Contracts and cooperative agreements
  A contract to reduce the noise generated by the scrubber fan system present on continuous mining machines.
• Low-Frequency Electromagnetic Noise Cancelling Antenna System
  11/22/2016 - Interagency agreements
  An interagency agreement to improve signal-to-noise in TTE receivers. The aim is to use existing transmitters that are not "intrinsically safe" to provide a reference signal from underground.
• Engineered Solutions - Dump Truck Vibrations and Impact on Operator Safety in High-Impact Shovel Loading Operations
  11/22/2016 - Contracts and cooperative agreements
  A contract to reduce or eliminate the impact of root mean square (RMS) accelerations due to vibrations on large dump truck operators during high-impact shovel loading operations.
• Evaluation and Development of Hearing Loss Interventions
  10/22/2016 - Research projects
  A project to improve the effectiveness of hearing loss prevention interventions through development, refinement, promotion, and long-term evaluation.
• Engineering Noise Controls for Longwall Mining Systems
  10/22/2016 - Research projects
  A project to develop durable noise controls that reduce the noise exposure of longwall mining system crews and facilitate the commercialization of the controls to make them available for all miners.
• Engineering Noise Controls for Haul Trucks and Load Haul Dumps (LHDs)
  10/22/2016 - Research projects
  A project to develop, evaluate, and implement engineering controls to reduce noise over-exposures among haul truck and LHD operators.
• Develop and Evaluate Engineering Noise Controls for Air Carbon Arc Cutting and Gouging
  10/22/2016 - Research projects
  A project to develop and evaluate noise controls and alternatives toward reducing sound pressure levels and personal noise exposures from air carbon arcing applications in the mining industry to below permissible exposure limit.
• Using Software to Predict Occupational Hearing Loss in the Mining Industry
  3/1/2016 - Peer reviewed journal articles
  This article by NIOSH discusses a software program that estimates the loss of hearing ability caused by occupational noise exposures.
• New Drill Bit Isolator Reduces Noise
  12/17/2013
  NIOSH-developed technology reduces drilling noise for coal mine roof bolting machines by 3-5 decibels. A drill bit isolator using this technology is now commercially available.
