22 SEBU7821-04Safety SectionOperator Station

The measurement for operator sound pressure levelwas obtained by using procedures that are specifiedin “ANSI/SAE J1166Oct98”. The procedure specifiesthe requirements of the work cycle to use whilethe measurement is obtained. The operator soundpressure level is 81 dB(A) for the cab that is offered

by Caterpillar. This reading is correct under thefollowing conditions: proper installation of the cab,proper maintenance of the cab, closed cab doors,and closed cab windows.

Hearing protection may be required when operatingwith an open operator station or when a cab is notproperly maintained. Hearing protection may also berequired when the cab doors and window are open or in a noisy environment.

The exterior sound pressure level for the standardmachine is 73 dB(A). The measurement wasobtained using the test procedures specified in “SAE

J88Jun86”. The measurement was obtained under the following conditions: distance of 15 m (49.2 ft),machine in middle gear range, and moving.
