汽车车内噪声声音品质的测试与评价
Measurement and Evaluation of Sound Quality of Interior Noise of Vehicle Cabin
【摘要】 研究车内噪声客观物理特征与人的主观感受之间的影响关系。通过对3种车型在不同行驶速度下的噪声进行实时录制,并在测试室采用成对比较的方法进行主观评价,同时提取其心理学评价指标,对车辆噪声的烦恼度影响因素进行了试验和分析。采用多元回归分析的方法分析心理学评价指标与主观烦恼度之间的关系。通过心理声学评价指标的线性组合得到的总评估值与主观评估值之间有很高的相关性,能很好地解释主观评估值,采用心理声学评价指标的线性组合对车辆声音品质进行主观评价是可行的。
【Abstract】 This paper studies the relations between the objective physical characters and the subjective feeling from interior noise of vehicle cabin. Three types of vehicle real-time noises were recorded at various running speeds and later being subjectively evaluated in the testing room by pair comparison method. Meanwhile, the psychological assessment indexes were extracted, and experiments and analysis on influencing factors of annoyance index of interior vehicle cabin noise were made. The relationship between psychological assessment indexes and subjective annoyance index were studied by multiple regression method. The synthetic evaluation values obtained by linear combination of psychological acoustic indexes were in good agreement with the measured subjective assessment values, which can better explain the subjective assess values. Subjective evaluation of vehicle sound quality by the linear combination of psychological acoustic assessment indexes is feasible.
