J1166_198707 SOUND MEASUREMENT-EARTHMOVING MACHINERY-OPERATOR-WORK CYCLE

This SAE Standard sets forth the procedures to be used only in measuring sound levels and the determination of the time weighted sound level at the operator station(s) of earthmoving machinery. Earthmoving machinery is defined per SAE J1057 JUN81. This standard is applicable to earthmoving machinery which has operator station(s) where the operator can either stand or sit and is transported by the machinery during operation. The standard describes the instrumentation requirements and specifies work cycles for earthmoving machinery. The standard describes the method used to calculate the time weighted average sound level at the operator station(s) identified in the practice as L_eq(5) for continuous operation of the work cycle. A method to relate the time weighted average sound level at the operator station(s) to operator sound exposure is also provided.
