Sound

Sound Standards (1) - Hearing protection may be needed when operating with open operator station & cab for extended periods or in noisy environment. The operator Equivalent Sound Pressure Level (Leq) is 76 dB(A) when SAE J1166 FEB2008 is used to measure the value for an enclosed cab. This is a work cycle sound exposure level. The cab was properly installed and maintained. The test was conducted with t
Sound Standards (2) - Exterior sound pressure power level for standard machine measured according to tests specified in ISO 6395:2008 is 116 dB(A). The exterior sound pressure level for the standard machine measured at a distance of 15 m (49 ft) according to the test procedures specified in SAE J88:2008, mid‑gear moving operation is 86 dB(A).
Sound Standards (3) - Operator Equivalent Sound Pressure Level is 79 dB(A) & 74 dB(A) with EU sound suppression applied when ISO 6396:2008 is used. Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in a noisy environment.
