The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed.
      Sound Standards (2)
      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)
      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.
