摘要
文章以汽车仪表板振动异响台架试验声样本为研究对象,分析了声样本的心理声学参数和烦恼度指标。运用成对比较法对声样本进行了主观评价,计算出各声样本的主观评价得分。通过主客观参数的相关分析和回归分析表明:仪表板作为复杂的内饰系统,其振动异响的性能受多参数影响,A计权声压级、响度、粗糙度、抖动度和烦恼度对主观评价得分均有影响;响度是描绘主观评价得分的最主要参量,响度会对主观评价得分产生显著的负向影响;响度是影响烦恼度的最主要因素,烦恼度这一综合评价指标对主观评价得分可以做出较为准确的预测。
Taking the test sound samples of the vehicle dashboard vibration abnormal sound bench as the research object,the psychoacoustic parameters and the annoyance index of the sound samples are analyzed.The pairwise comparison method is used to subjectively evaluate the sound samples,and the subjective evaluation score of each sound sample is calculated.Correlation analysis and regression analysis of subjective and objective parameters show that the instrument panel is a complex interior system,and its vibration and abnormal noise performance is affected by multiple parameters.A-weighted sound pressure level,loudness,roughness,jitter,and annoyance all affect the subjective evaluation score;Loudness is the most important parameter to describe the subjective evaluation score,which have a significant negative impact on the subjective evaluation score.Loudness is the most important factor affecting the annoyance.Annoyance,a comprehensive evaluation index,can make an accurate prediction to the subjective evaluation score.
