• A noise control package for vibrating screens
  3/1/2013 - Peer reviewed journal articles
  NIOSH researchers have developed a suite of noise controls for vibrating screens consisting of constrained layer damping (CLD) treatments, a tuned mechanism suspension, an acoustic enclosure, and spring inserts.
• 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.
• Structural Vibration as a Noise Source on Vibrating Screens
  11/1/2009 - Conference papers
  For horizontal vibrating screens, NIOSH testing indicates that the screen sides and feed box are dominant noise sources for the 250 Hz through 800 Hz one-third octave bands, while the electric motor is the most significant source for the 1 kHz band.
• Assessment of Engineering Noise Controls at a Talc Processing Plant
  4/1/2009 - Peer reviewed journal articles
  This report describes an investigation by NIOSH researchers to quantify sound levels and to determine the amount of sound reduction provided by engineering noise controls installed in a talc processing plant.
• Improving the Performance of Fan-Powered Dust Collectors in Stone-Cutting Applications
  6/1/2008 - Conference papers
  The objective of the research was to cost-effectively increase the air cleaning volume and improve dust capture efficiency of an off-the-shelf dust collector with a larger motor and blower.
• Survey of Noise in Coal Preparation Plants
  1/1/2007 - Peer reviewed journal articles
  Noise surveys were conducted in eight coal preparation plants. Results indicate that only workers who routinely spend a significant portion of their shift in the plants (away from the control rooms) are susceptible to overexposure from noise.
• Lower Respirable Dust and Noise Exposure with an Open Structure Design
  11/1/2006 - Reports of Investigations
  This report discusses the evaluation of three types of product sizing silica sand structures: a masonry design, a steel-sided design, and an open structure design. An open structure design was superior from both a dust and noise standpoint.
• Noise and Vibration Reduction of a Vibrating Screen
  1/1/2005 - Peer reviewed journal articles
  This paper reports on a cooperative study on vibrating screen noise conducted at a coal preparation plant. Rubber isolators were found to reduce sound levels by 1 dB and amped side plates reduced vibration levels on the screen sides by 1 to 7 dB(A).
