摘要
拟研究电动汽车座舱内部噪声特性对声学舒适性的影响.通过道路试验获取4种典型路面工况下某型电动汽车在不同车速下的舱内噪声,计算分析其心理声学参数,开展烦恼度主观评价实验,并基于非线性Zwicker心理声学烦恼度及其修正模型进行建模研究.结果显示,随着车速和路面粗糙程度变大,响度逐渐提高,尖锐度也随车速增大而变大;Zwicker心理声学烦恼度模型更适用于电动汽车座舱内部噪声.
Abstract
The influence of internal noise characteristics of the cabins of electric vehicles on the acoustic comfort is studied.The interior noise of the cabin of an electric car running at different speeds under different road conditions is measured.Afterwards,the psychoacoustic parameters of the noise are calculated and analyzed,and the subjective annoyance evaluation experiment with the noise as the stimuli is conducted.On this basis,a nonlinear annoyance model for evaluating the electric vehicle interior noise is established in virtue of the psychoacoustic annoyance model proposed by Zwicker.The results of the analysis of the model indicate that the loudness of the noise increases with the increase of the running speed and the roughness of the road surface,and the sharpness of the noise also increases with the increase of the running speed.The Zwicker's psychoacoustic annoyance model is more appropriate for electric vehicle interior noise analysis.
