• Description:
  The interior noise of an underground mine rail-operated personnel carrier (mantrip vehicle) was cost effectively reduced by replacing some standard components with acoustically treated components. The noise control features included a softer suspension, softer motor mounts, damped panels, sound-absorbing motor enclosures, and helical gears. Depending on operating conditions, the modified vehicle was 6 to 7.5 dBA quieter than an unquieted mantrip. The noise level in the mantrip interior was reduced to approximately 85 dBA at an average vehicle speed. These noise control features increased the overall mantrip cost by less than 5 pct.
