• From Development to Evaluating Effectiveness in Industry: Building a Research Model for Noise Control Technology Efforts
  4/1/2010 - Conference papers
  A research model was developed to include metrics to evaluate and measure the effectiveness of noise control technologies. This model can be used to assess the development, dissemination, and evaluation of noise control technologies.
• 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.
• Acoustic Assessment of Pneumatic and Electric Jackleg Drills used in the Mining Industry
  4/1/2010 - Conference papers
  This paper presents an acoustic assessment of pneumatic and electric jackleg drills involving Noise Source Identification (NSID), penetration rate measurements, operator’s cumulative noise dose measurements, and determination of sound power levels.
• 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.
• A Control Suite to Reduce Roof Bolting Machine Drilling Noise
  4/1/2010 - Conference papers
