• NIOSH Tools For Hearing Loss Prevention Programs
  2/1/2010 - Conference papers
  NIOSH has developed several new hearing loss prevention tools and interventions that specifically target behavioral and attitudinal barriers that keep miners from effectively acting to prevent their own hearing loss.
• A Dual Sprocket Chain as a Noise Control for a Continuous Mining Machine
  9/1/2009 - Peer reviewed journal articles
  A dual sprocket conveyor chain for a CMM was examined both in the laboratory and in underground field studies to test the influence on lowering the sound power emissions of the chain conveyor of a CMM when compared to a standard chain.
• Noise Source Identification on a Horizontal Vibrating Screen
  7/1/2009 - Peer reviewed journal articles
  This paper presents the results of a NIOSH study in collaboration with Acoustical and Vibrations Engineering Consultants Inc. (AVEC) to determine the dominant noise sources on a vibrating screen machine at low frequencies, i.e., 250 to 1,000 Hz.
• A Technique for Estimating the Sound Power Level Radiated by Pneumatic Rock Drills and the Evaluation of a CSIR Prototype Rock Drill with Engineering Noise Controls
  5/1/2009 - Peer reviewed journal articles
  This report describes research by NIOSH to reduce the noise exposures of jackleg drill operators and to prevent additional cases of noise induced hearing loss (NIHL) by developing and evaluating low-cost retrofit noise controls for equipment.
• Application of Phased Array Technology for Identification of Low Frequency Noise Sources
  10/1/2008 - Conference papers
  This paper describes research to control dominant noise sources in continuous miners. This work ranks noise radiated by different conveyor sections and determines the effect of a urethane-coated tail roller on the noise radiated by the tail section.
• Noise Source Identification on a Continuous Mining Machine
  7/1/2008 - Conference papers
  In the Hemi-anechoic chamber of the Pittsburgh Research Laboratory noise source identification on a continuous miner was performed using phased array measurements and a frequency domain beamforming algorithm with Diagonal Removal.
• Continuous Mining Machine Conveyor System Sound Power Levels
  7/1/2008 - Conference papers
  This paper describes the results of different chain types and configurations installed on a continuous mining machine conveyor system and the resulting sound power levels.
• Snapshot of Noise and Worker Exposures in Sand and Gravel Operations
  3/1/2008 - Peer reviewed journal articles
  This paper presents research examining noise on dredges used in several surface mine sand and gravel operations and in the processing facilities.
• NIOSH Hearing Loss Simulator Instruction and Training Guide
  3/1/2008 - NIOSH/USBM numbered publications
  This user manual explains objectives that can be addressed with the NIOSH Hearing Loss Simulator and training scenarios applied to real-life, real worker scenarios. This guide explains the simulator's functions in detail.
• Application of Prevention through Design for Hearing Loss in the Mining Industry
  2/1/2008 - Peer reviewed journal articles
  This paper describes the quiet-by-design approach of a noise control that reduced exposures of continuous mining machine operators by 3dB(A) using the four functional areas of Prevention through Design - Practice, Policy, Research, and Education.
