摘要
声品质是地铁车内乘坐舒适性的一项重要指标。以地铁列车车内噪声为研究对象,探讨声品质的主观模糊综合评价方法。以上海地铁9号线为例,考虑地铁运行的三种工况、两种乘客乘坐姿态,分别测取车内不同位置的噪声信号,采用分组成对比较法对测点噪声进行主观评价实验和模糊综合,计算得出地铁整车的烦恼度评价综合值,可用以实施不同列车的声品质比较和评判。所提出的方法对地铁声学设计和提高乘坐舒适性提供参考。
Interior sound quality of vehicles is an important measure for evaluating the riding comfort in subways. In this paper, a fuzzy comprehensive method for subjective sound quality evaluation is investigated for its application to subway interior noise evaluation. The interior noise signals for 3 different operating conditions and two passenger’s attitudes （sitting and standing） are recorded respectively in 4 locations in a subway car of Shanghai Metro Line 9. Subjective assessments are carried out by the grouped pair-comparison method and a fuzzy comprehensive evaluation approach. The global value of the subway annoyance is derived, which may be applied as a reference for synthetic judgment and comparison of the sound quality in different subways. The proposed method is instructive and useful for the acoustic design and ride comfort improvement in the subway’s sound quality evaluation （SQE）.
