Title: A Noise Control Study of Certain Diesel-Powered Strip Mine Vehicles
text: This paper describes the work performed in three distinct noise studies on typical diesel-powered strip mining equipment and discusses their results. Mufflers lowered diesel exhaust noise exposure for adjacent workers and the community at large, but had little effect on the noise level at the operator's position. Properly designed and installed noise control kits can be an effective method of reducing the operator's exposure to an acceptable level, and can simultaneously dampen vibration inside the cab.
