烦恼度作为评价噪声对人影响的重要指标,受到广泛重视并获得应用。通过主观评价实验和数据统计分析,从音色角度对城市典型车辆噪声烦恼度进行建模并给予物理解释。研究发现:(1)车辆噪声烦恼度音色空间由四个维度构成;(2)利用多元线性回归方法给出的车辆噪声烦恼度模型与声样本烦恼度拟合较好;(3)烦恼度空间维度与特定频谱特性具有较高的相关性。研究结果为车辆噪声烦恼度建模及降噪设计提供了新的思路。
Annoyance as an important indicator of noise impact on people, has been widely valued and applied. Through the subjective evaluation experiment and statistical analysis of data, the urban car noise annoyance is modeled and given a physical explanation from the sound color point of view. The results show that: (1) the vehicle noise annoyance tone space consists of four dimensions; (2) the annoyance model of vehicle noise given by the multiple linear regression method fits well with the acoustic sample annoyance degree; (3) The dimension has a high correlation with a particular spectral characteristic. The results provide a new idea for vehicle noise annoyance modeling and noise reduction design.
