电动汽车座舱内部噪声的非线性心理声学烦恼度建模
The Nonlinear Psychoacoustic Annoyance Modeling of Interior Noise of the Electric Vehicle Cabins
摘要
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.关键词
