Abstract：
Kyushu Shinkansen and conventional railway lines run parallel in the areas 5 km north of Kumamoto Station (northern area) and 12 km south of the station (southern area). Following the operation of the Kyushu Shinkansen Line in 2011, the adjacent conventional railway line in the north was elevated, a new station was operated in the south, and large earthquakes struck the Kumamoto area from March to April 2016. Sleep disturbances were compared before and after the interventions and earthquakes based on noise source (Shinkansen and conventional railways), area (northern and southern), and house type (detached and apartment) through socio-acoustic surveys from 2011 to 2017. The Shinkansen railway caused significantly less sleep disturbances in detached houses in the north after compared to before the earthquakes, presumably due to more frequent closures of bedroom windows in northern detached houses following the earthquakes. The Shinkansen railway caused significantly more sleep disturbances in apartments in the south after compared to before the earthquakes, presumably because the Shinkansen slowed down immediately after the earthquakes and returned to normal speed during the survey, suddenly increasing the noise exposure. There was no significant difference in the other six cases investigated. Overall, the interventions may not have caused significant differences in sleep disturbances. This article expands on the congress paper by Morihara et al. presented in the \"Community Response to Noise\" session at the 52nd International Congress and Exhibition on Noise Control Engineering in Makuhari, Japan, organized by the International Institute of Noise Control Engineering.
摘要：
九州新干线和常规铁路线在熊本站以北5公里（北部地区）和站以南12公里（南部地区）的地区平行运行。继2011年九州新干线运营后,北边相邻的常规铁路线被高架,在南部运营了一个新车站，2016年3月至4月，熊本地区发生了大地震。根据噪声源（新干线和常规铁路）比较干预和地震前后的睡眠障碍，地区（北部和南部），和房屋类型（独立和公寓）通过2011年至2017年的社会声学调查。与地震前相比，新干线铁路在北部的独立式住宅中造成的睡眠障碍大大减少，大概是由于地震后北部独立式房屋的卧室窗户更频繁地关闭。与地震前相比，新干线铁路在南部的公寓中造成了更多的睡眠障碍，大概是因为新干线在地震发生后立即减速，并在测量过程中恢复正常速度，突然增加噪声暴露。在调查的其他六个案例中没有显着差异。总的来说,这些干预措施可能不会导致睡眠障碍的显著差异.本文扩展了森原等人的国会论文。在Makuhari举行的第52届国际噪声控制工程大会和展览会上的“社区对噪声的反应”会议上提出，Japan,由国际噪声控制工程研究所组织。
