• Analysis of Nonstandard Noise Dosimeter Microphone Positions
  3/1/2008 - Peer reviewed journal articles
  This study, conducted as part of a project to evaluate a new type of noise exposure monitoring paradigm, showed that the effects of dosimeter microphone placement in a diffuse field were found to be minor for most of the test microphones/locations.
• Results of Noise Measurements from Underground Testing of a Roof Bolting Machine Duty Cycle
  10/1/2007 - Conference papers
  This 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.
• Heavy Construction Equipment Noise Study Using Dosimetry and Time-Motion Studies
  7/1/2007 - Peer reviewed journal articles
  This research determined noise exposures of equipment operators while documenting worker task. The types of equipment studied included asphalt pavers, backhoes, bulldozers, compaction equipment, excavators, haul trucks, and wheeled loaders.
• Heavy Construction Equipment Noise Study Using Dosimetry and Time-Motion Studies
  10/1/2005 - Conference papers
  The 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).
