某汽车空调单体音调噪声的烦恼度评价研究

Research on annoyance evaluation of tone noise of an automobile air conditioner

针对汽车空调工作时产生的音调噪声会使驾乘人员产生烦恼感,对某汽车空调单体的音调噪声烦恼度模型进行研究。首先采用模拟噪声的方法解决实际噪声样本不足的问题,然后通过主客观评价和相关性分析,建立了汽车空调单体音调噪声的烦恼度模型。研究表明:汽车空调单体的音调噪声烦恼度主要受音噪比和响度的影响;通过该模型能够准确预测汽车空调单体音调噪声对人耳造成的烦恼度数值。

In view of the fact that the tonal noise generated when the car air conditioner is working can cause passengers to feel annoyed,this paper studies the annoyance model of the tonal noise of a single car air conditioner.Firstly,the method of simulated noise is used to solve the problem of insufficient actual noise samples,and then through subjective and objective evaluation and correlation analysis,the annoyance model of single-tone noise of automobile air conditioner is established.The research results show that the annoyance of the tone noise of a single car air conditioner is mainly affected by the sound-to-noise ratio and loudness;the model can accurately predict the annoyance degree of the tone noise of the single car air conditioner to the human ear.
