以6种B级轿车在不同车速下匀速行驶时的车内噪声样本为评价对象,采用成对比较法对B级轿车的噪声品质偏好性进行了主观评价试验,计算了各噪声样本的主要心理声学客观参数,并通过线性相关分析和多元回归分析,建立了噪声偏好性主观评价的数学模型。研究表明,在匀速工况下B级车的噪声品质偏好性主要受响度和尖锐度两个参数影响。
Taking the noise samples of six B-class cars at different vehicle speeds at a constant speed as the evaluation objects, the paired comparison method was used to evaluate the noise quality preference of the B-class sedans. The main psychology of each noise sample Acoustic objective parameters, and through the linear correlation analysis and multiple regression analysis, the mathematical model of the subjective evaluation of noise preference is established. The research shows that the noise quality preference of the B-class car under the constant speed condition is mainly affected by the two parameters of loudness and sharpness.
