摘要
利用人工头记录了同一辆轿车安装5种不同消声器时车内后排左侧座位处的噪声信号,采用成对比较法对所记录的声信号进行了主观烦恼度评价,通过聚类分析和因子分析,得到了影响烦恼度的主要客观参量,并在此基础上利用多元逐步回归方法建立了以客观参量来表征主观烦恼度的数学模型。
Five different exhaust mufflers are installed on a same car,and noise signals are recorded by an artificial head located at rear left passenger seat.Subjective annoyance evaluation is conducted on the sound signals recorded by paired comparison method,and major objective parameters affecting subjective annoyance are identified through cluster analysis and factor analysis.Based on this,a mathematical model for expressing subjective annoyance by objective parameters is built by using multiple stepwise regression technique.
