• Underground Evaluation of Coated Flight Bars for a Continuous Mining Machine
  12/1/2006 - Conference papers
  A highly durable polyurethane coating has been developed for chain flights to decrease noise from metal-on-metal impacts. This paper evaluates this engineering noise control in reducing the noise exposure of continuous mining machine operators.
• Summary of Longwall and Continuous Miner Section Noise Studies in Underground Coal Mines
  11/1/2006 - Peer reviewed journal articles
  This report summarizes the results of noise surveys, consisting of full-shift worker noise exposure, time-motion studies, and equipment noise profiling for longwall and continuous miner sections in six underground coal mines.
• Limestone Mining: Is It Noisy or Not?
  10/1/2006 - Peer reviewed journal articles
  This article describes noise research conducted in limestone mines, detailing the equipment likely to cause worker overexposures, the occupations experiencing overexposures, and the implications for worker noise exposure reduction.
• Sound Power Level Study of a Roof Bolter
  1/1/2006 - Peer reviewed journal articles
  NIOSH initiated a study of a roof bolter to reduce noise exposure to mine roof bolter operators. When drilling into granite, it was found that wet drilling generated lower sound power levels and performed better than vacuum drilling.
• Working in Noise with a Hearing Loss: Perceptions from Workers, Supervisors, and Hearing Conservation Program Managers
  12/1/2005 - Peer reviewed journal articles
  This study outlines potential challenges regarding job safety and hearing conservation practices for noise-exposed, hearing-impaired workers.
• Administrative Controls for Reducing Worker Noise Exposures
  12/1/2005 - Peer reviewed journal articles
  This publication describes worker noise exposure surveys in coal mines and coal preparation plants, revealing that worker dosimetry, time-motion studies, and equipment noise profiling are important for effective use of administrative controls.
• Noise Exposure and Overhead Power Line (OPL) Safety Hazards at Surface Drilling Sites
  11/1/2005 - Information Circulars
  This is a series of 5 separate double sided sheets designed to educate workers about noise exposure and overhead power line safety at surface drilling sites.
• Heavy Construction Equipment Noise Study Using Dosimetry and Time-Motion Studies
  10/1/2005 - Conference papers
  The focus of this research was to determine the noise exposures of heavy construction equipment operators while documenting the workers’ tasks, (i.e. hauling, moving, and/or pushing construction material).
• Hearing Loss in the Mining Industry: Overview of the NIOSH Hearing Loss Prevention Program at the Pittsburgh Research Laboratory
  10/1/2005 - Conference papers
  This paper provides an overview of the NIOSH hearing loss prevention program being conducted at NIOSH PRL.
• Water Well Safety Bits: Health And Safety Information For The Water Well Industry
  9/1/2005 - Information Circulars
  Water well drillers are exposed to high levels of noise while working. Drillers and owners can work together to prevent noise-induced hearing loss, and measures can be taken to reduce exposure to hazardous noise.
