| 摘 要： | 本研究对匀速、加速及减速3种行驶状态磁悬浮列车噪声分别进行了双耳效应采样,并于实验室中测试被试对样本主观感受。结果表明,3种行驶状态列车噪声样本的主观烦恼度与LA均具有较好的关联度。比较加速段与减速段样本,前者的主观烦恼度要高于后者,且在等主观烦恼度水平下,前者比后者要低大约2.5~4.5dBA。对于3种行驶状态样本总体而言,主观烦恼度与LA10的相关系数最高(R=0.981),略高于主观烦恼度跟LA与LAmax的相关系数,建议采用LA10作为磁悬浮列车噪声排放限值的评价指标。

| Abstract: | In this study,passby sounds were sampled binaurally when magnetic levitation trains(MLT) ran at even and varied speed.Then,the annoyance caused by the sounds was investigated in the laboratory.As the results shown,at the same running status,there was a strong correspondence between the annoyance and the LA of passby sounds.The annoyance caused by MLT when accelerating was higher than that caused by the decelerating MLT.And with the same annoyance rating,the LA of the former was approximately 2.5~4.5dBA less than those of the latter.Regardless of the running status,the correlation coefficient between the annoyance rating and the LA10 of total passby sounds was highest(R=0.981),which was slightly higher than those between the annoyance rating and the LA and LAmax.Thus,it is suggested that LA10 could be selected as the evaluation indicator for emission limits of MLT sounds. |
