||Noise exposure profile among heavy equipment operators, associated laborers, and crane operators
||Nov. 1998, Vol.59, No.11, p.774-778. Illus. 14 ref.
||In a survey of construction sites in Quebec, Canada, the average daily noise exposure was 84 to 99dBA for heavy equipment operators, 90dBA for labourers and 74 to 97dBA for crane operators. The main sources of noise to which heavy equipment operators are exposed are vehicle engines and the muffler exhaust system, usually located near the operator. The presence of insulated cabs such as those found on power shovels, backhoes and wheel loaders and graders helps to reduce noise exposure. The noise exposure of labourers is determined by the type of task, the manual equipment used and noise from surrounding heavy equipment. In the case of crane operators, an insulated cab significantly reduces exposure to engine noise.
