NTIS: PB/82-137019 :35 pages
The two volumes of this report summarize the noise control work performed on a rail personnel carrier operated in coal mines. Volume I describes the aboveground work performed to identify the noise sources, design, fabricate, and install and evaluate the treatments through noise and vibration tests. Volume II describes the underground work conducted to determine the deterioration, if any, of the treatments when the vehicle was operated normally in a mine. There were no significant changes in the acoustical performance or mechanical integrity of the treatments at the end of a 3-month period.
