| 摘 要： | 以4种类型柴油机在不同运行工况时机器旁1 m处噪声采集样本为评价对象,对柴油机噪声烦躁度用等级评分法进行了主观评价试验,分析计算了各噪声样本的主要心理声学客观参数,并通过相关分析和多元回归分析,建立了烦躁度评价数学模型。研究表明,稳态工况下柴油机噪声烦躁度主要受响度和尖锐度两个心理声学参数影响。

| Abstract: | The noise sampled in 1 m position beside four types of diesel engines at different operation conditions were selected for evaluation. The subjective evaluation test of diesel engine noise annoyance was carried out with grading estimation. Several primary objective psycho-acoustical parameters of these samples were analyzed and calculated. Through correlation and multi-dimensional regression analysis, a mathematical model for noise annoyance evaluation was established. The research results indicate that the diesel engine noise annoyance under the steady operation conditions is affected by two psycho-acoustical parameters： loudness and sharpness. |
