7/1/2008 - Conference papersIn 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.
-
7/1/2008 - Conference papersThis paper describes and evaluates an engineering noise control for the roof bolting machine, namely the collapsible drill steel enclosure.
-
7/1/2008 - Conference papersThis study examines the use of a commercially-available lubricant for hearing aids to determine whether it would facilitate improved fit and attenuation for earplugs.
-
7/1/2008 - Conference papersThis paper provides detailed information on the findings of NIOSH research measuring the sound power level generated by a horizontal vibrating screen with the screen either directly on the floor or on rubber isolation pads.
-
11/1/2007 - Conference papersThis paper details laboratory noise testing results of a continuous mining machine conveyor system which uses a coating for the tail roller designed to help bring the continuous mining machine into compliance with federal noise regulations.
-
10/1/2007 - Conference papersThis paper evaluates the duty cycle of a typical roof bolting machine operation at two coal mines. The results provide insight into which portion of the operators’ duty cycle is the most prominent contributor to noise exposure.
-
10/1/2007 - Conference papersThis paper provides a method for predicting sound pressure levels at the operator’s position of a roof bolting machine in an underground coal mine using sound power levels determined in the laboratory.
-
10/1/2007 - Conference papersThis paper discusses the methods NIOSH used to identify noise sources on a roof bolting machine while drilling.
-
12/1/2006 - Conference papersA 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.
-
10/1/2005 - Conference papersThe 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).
