摘 要：为了更好地了解纯电动城市客车内部职业卫生噪声暴露水平，本文基于声压级测量法和频谱分析法，对16个车次的北京纯电动城市客车内部的噪声水平进行测量。结果表明，从A计权看，车辆内部声环境与十年前相比已有明显改善，低频、中频噪声有明显降低，且中频及高频噪声覆盖范围未有较大变化；从C计权看，客车内部噪声中的低频噪声占比较大。

Abstract: To better understand the occupational health noise exposure levels of pure electric city buses,this paper measures the intern or noise levels of 16 trips for Beijing's pure electric city buses based on sound pressure level measurements and spectral analysis.The results show that,from the perspective of A weight,the internal acoustic environment of the vehicles has significant improvement compared to ten years ago,with notable reductions in low-frequency and medium-frequency noise.The coverage of medium-frequency and high-frequency noise has not changed significantly.From the perspective of C weight,the low-frequency noise inside the vehicles has a relatively large proportion.
Key words: pure electric bus; occupational health; noise exposure level
