摘要
测试了韩国高速列车在各种运行条件下车内噪声的声品质。为查明利用评判组测验的主观方法与基于心理声学(如响度、尖锐度)的预测方法的相关关系,进行了主观评价试验,判定响度级比声压级更适宜评价声学舒适性。
The sound quality of interior noise in Korean high-speed trains under different operation conditions is measured.A subjective assessment test is performed in order to find out the correlation between the subjective method using ajury test and the predictive method based on psychoacoustic parameters such as loudness and sharpness.It is determined that loudness levels are a better assessment of acoustic comfort than sound pressure levels.
