10/1/2009 - Peer reviewed journal articlesThis study examines noise exposure inside haul truck cabs during a typical workday involving normal operator practices, the effect of cab noise reduction features, the consequence of disabling noise controls, and the significance of maintenance.
-
9/1/2009 - Peer reviewed journal articlesA dual sprocket conveyor chain for a CMM was examined both in the laboratory and in underground field studies to test the influence on lowering the sound power emissions of the chain conveyor of a CMM when compared to a standard chain.
-
7/1/2009 - Technology NewsNIOSH has been performing research to analyze and reduce hazardous noise exposure in mines.
-
7/1/2009 - Peer reviewed journal articlesThis paper presents the results of a NIOSH study in collaboration with Acoustical and Vibrations Engineering Consultants Inc. (AVEC) to determine the dominant noise sources on a vibrating screen machine at low frequencies, i.e., 250 to 1,000 Hz.
-
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.
-
5/1/2009 - Peer reviewed journal articlesThis report describes research by NIOSH to reduce the noise exposures of jackleg drill operators and to prevent additional cases of noise induced hearing loss (NIHL) by developing and evaluating low-cost retrofit noise controls for equipment.
-
1/1/2009 - Peer reviewed journal articlesThis paper describes NIOSH research to evaluate noise generated by a roof bolting machine and its components. Results are given for two engineering controls for the roof bolting machine: a bit isolator and a drill chuck isolator.
-
12/1/2008 - Technology NewsNational Institute for Occupational Safety and Health (NIOSH) has been performing research to improve the level of hearing protection by providing workers with an inexpensive, easy-to-use device to check earplug fit.
-
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.
-
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.
