ABSTRACT

A number of studies carried out on noise measurement and its control in the past reflect bulldozers, dumpers, and front-end-loaders as the major sources of noise in open-pit mines (Daniel et  al., 1979; Bartholomae and Bobick, 1983; Aljoe et al., 1985 and Valoski, 2000). The above-mentioned studies also indicated major sources of noise in diesel-powered equipments as the exhaust, cooling fan, engine, air inlet, transmission, final drive, and the main frame. Noise from these sources reach the operator via airborne as well as structure-borne paths.
