5/1/2009 - NIOSH/USBM numbered publicationsThis manual describes the Determination of Sound Exposures (DOSES) software developed by NIOSH for use by mine management and safety personnel to simplify record keeping and analysis associated with time-motion studies and worker noise exposures.
-
4/1/2009 - Peer reviewed journal articlesThis 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.
-
7/1/2008 - Conference papersIssues related to testing the performance of sound restoration hearing protectors are outlined within this paper, and possible solutions are discussed.
-
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 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.
-
3/1/2008 - Peer reviewed journal articlesThis paper presents research examining noise on dredges used in several surface mine sand and gravel operations and in the processing facilities.
-
12/1/2007 - Peer reviewed journal articlesThis paper discusses the results of a collaboration with a local drilling company to design and install a partial cab between the operator and the drill steel in an effort to reduce the sound level at the operator station of a surface drill rig.
