12/1/2006 - Conference papersThis paper presents a method using a ray-tracing technique to determine absorption coefficients for underground mines. Absorption coefficients are determined and presented for octave bands from 63 Hz to 8 kHz.
-
4/1/2010 - Conference papersA 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.
-
4/1/2010 - Conference papersNIOSH is developing noise controls to reduce noise generated by horizontal vibrating screens. This paper documents testing of the stiffeners.
-
4/1/2010 - Conference papersThis 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.
-
4/1/2010 - Conference papersNIOSH conducted research to reduce the noise emission of various underground coal-mining equipment and developed a suite of controls to reduce drilling noise.
-
4/1/2010 - Conference papersThe paper documents NIOSH research to date of a damped drill steel on a roof bolting machine.
-
11/1/2009 - Conference papersNIOSH is developing bit and chuck isolators to reduce vibration, and thus noise radiation of the drill steel, with the longer-term goal of reducing roof bolting machine operator noise exposure.
-
11/1/2009 - Conference papersThis paper describes NIOSH research to develop noise controls for mining equipment whose operators exceed the Permissible Exposure Level (PEL). Two alternative approaches are explored to the conventional beamforming algorithm.
-
11/1/2009 - Conference papersFor 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.
-
10/1/2008 - Conference papersThis 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.
