Sound Level for Enclosed Cab

The operator sound pressure level is measured at the recommended operating engine speed of 2200 rpm.

The measurement for operator sound pressure level was obtained by using procedures that are specified in "ANSI/SAE J1166Oct98". The procedure specifies the requirements of the work cycle to use while the measurement is obtained. The operator sound pressure level is 81 dB(A) for the cab that is offered by AVSpare. This reading is correct under the following conditions: proper installation of the cab, proper maintenance of the cab, closed cab doors and closed cab windows.

Hearing protection may be required when operating with an open operator station or when a cab is not properly maintained. Hearing protection may also be required when the cab doors and window are open or in a noisy environment.

The exterior sound pressure level for the standard machine is 73 dB(A). The measurement was obtained 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.
