Sound Level for Enclosed Cab
The operator sound pressure level is measured at the recommended operating engine speed of 2100 rpm.The measurement for operator sound pressure level (Leq) was obtained by using procedures that are specified in "ANSI/SAE J1166" May 1990The procedure specifies the requirements of the work cycle to use while the measurement is obtained. The operator sound pressure level is 80 dB(A) for the cab that is offered by Caterpillar. 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.The operator sound pressure level was measured according to the procedures that are specified in "SAE J919" June 1986. The 81 dB(A) measurement is for the cab that is offered by Caterpillar. This reading is correct under the following conditions: proper installation of the cab, proper maintenance of the cab, closed cab doors, closed cab windows, machine in middle gear range, and moving.The exterior sound pressure level for the standard machine is 73 dB(A). The measurement was obtained using the test procedures specified in "SAE J88" June 1986. The measurement was obtained under the following conditions: distance of 15 m (49.2 ft), machine in middle gear range, and moving.Sound Performance for Machines Offered in European Union Countries and in Countries that Adopt the EU Directives

Model Sound Level
424B2 with Utility Cab 82db (A)
Aspiration Turbocharged The operator sound pressure level is measured according to dynamic test procedures and conditions specified in "ISO 6396" or "95/27/EC". The operator sound pressure level is measured at the recommended operating engine speed of 2100 rpm.As manufactured by Caterpillar, the exterior sound power level of the machine meets the criteria specified in the European Directives noted on the certificate of conformance and the accompanying labels.Vibration Level
The hands and arms are exposed to a weighted root mean square acceleration that is less than 2.5 m/s2.The whole body is exposed to a weighted root mean square acceleration that is less than 0.5 m/s2.Measurements are obtained on a representative machine using the procedures in the following standards:
"ISO 2631"
"ISO 5349"
"SAE J1166"
