摘　　要：根据轻轨车辆噪声的现状及特点,本文认为轻轨车辆的噪声仍以A声级评价为宜,但需规定容许的倍频程带声压值,以抑制低频噪声对人体的影响,同时提出了轻轨车辆噪声的控制标准。最后还指出了A声级评价总体的缺陷,建议应以人体工程学为基础,综合考虑噪声对人体的多方面危害,以制定出更完善的轻轨车辆噪声评价标准。According to the present situation and features of the noise of light rail vehicles,to criticize the noise of light rail vehicles with sound level A is still suitable.But the allowable values of the sound pressure of octave band must be stipulated in order to restrain the influence of low-frequency noise on human body.Mean- while,the standards controlling the noise of light rail vehicles are provided.At last,points out some defects of critcrion with sound level A,and proposes to draw up a more perfect criterion for noise of light rail vehicles.
