Abstract
There is a great pressure on the prevention and control of urban road traffic noise pollution.At present,under the implementation of the concept of low-carbon environmental protection in China,new energy vehicles are popularized.The noise principle of new energy vehicles is different from that of traditional fuel vehicles.In this paper,according to the sound energy superposition principle and 1 h equivalent continuous A sound level,the passing noise samples of internal combustion engine vehicles and new energy vehicles are collected,and a certain area of the city for acoustic model prediction is selected through on-site measurement,and using road traffic flow and other methods,we studied the impact of the proportion of new energy vehicles on the regional acoustic environment.关键词
