摘　　要：通过对临近地铁居民现场问卷调查及住宅内进行的室内二次辐射噪声实测结果统计,分析了不同因素对地铁引起室内二次辐射噪声对居民生活的影响。探讨了在不同噪声评价量下,地铁引起室内二次辐射噪声的声压级随楼层及距离的衰减。根据室内噪声的实测结果与居民对室内噪声的烦恼度反应,计算了现行标准中室内噪声的不同评价量的烦恼度阈值,为今后更加深入和全面地研究地铁引起的二次辐射噪声烦恼度及其评价标准问题提供了基础资料。Through statistical analyses on questionnaire and in-situ measure results of ground-borne noise in buildings caused by subway,effects on living condition of inhabitants under different factors were studied. Attenuation between sound pressure level of ground-borne noise and floor and distance from the tunnel center line was discussed. Based on measurement results and reaction of annoyance for inhabitant to ground-borne noise, the annoying threshold to different assessment value in current standard of ground-borne noise were calculated. It is the basis for ground-borne noise annoyance research and its evaluation criterion.
