Abstract: Special purpose vehicles have brought great challenges to vehicle noise management and control due to their multiple models, wide functions and complex use scenarios. Through combing China's special-purpose vehicle standards, this paper focuses on the analysis of China's specialpurpose vehicle noise limits and operating noise measurement methods. The current operating noise limits and measurement methods have the characteristics of long standard age, old indicators, and large differences in measurement methods, which do not meet the current market situation and the needs of operation noise management and control. Combined with domestic noise pollution management and the development trend of international automobile noise standards, this paper suggest that relevant domestic institutions should carry out targeted research as soon as possible, formulate unified special-purpose vehicle operating noise limits and measurement method standards in a timely manner, and seize international research hotspots.
