Noise control of an underground mine personnel carrier.
Galaitsis AG; Bobick TG
Noise Control Eng J 1983 Jan; 21(1):4-9
The interior noise of a mine-operated rail personnel carrier was reduced by replacing some standard components with acoustically treated components. The latter 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 vehicle. The noise level in the vehicle interior was reduced to approximately 85 dba at an average vehicle speed.
