基于掩蔽效应的汽车非平稳车内噪声烦恼度评价方法
Annoyance Subjective Evaluation Method of Automotive Interior Nonstationary Noises Based on Human Auditory Masking Effect
摘要
Abstract
Based on the collected interior noises of passenger cars running at accelerating or constant speeds,a subjective evaluation test of vehicle noise annoyance was conducted using anchored semantic differential method herein.Considering masking effect and questionnaire results of the sound quality subjective estimation experiments,the average values of time-varying psychoacoustic parameters of noise samples at constant speeds and the second half of the accelerating noise samples were calculated as independent variables,a regression mathematical relation among the average values and subjective evaluation results of annoyance was built using SVM technique.A masking effect based annoyance evaluation method (ME-AE method) was developed.Furthermore,by calculating average values of time-varying psychoacoustic parameters of all noise samples,a psychoacoustic metrics based annoyance evaluation method (PM-AE method) was developed using SVM.Results of leave-one-out and 10-fold cross-validating experiments suggest that the two annoyance subjective evaluation methods are effective in predicting vehicle interior nonstationary noises with high accuracy.And the proposed ME-AE method is more accurate and stable.Especially for predicting the annoyance of acceleration noises,the new method achieves greater improvements.关键词
