Cross-regional comparison of community response to road traffic noise

为了澄清以下两点，对日本寒冷和温暖地区的公寓楼和独立式住宅进行了为期两年的道路交通噪声社会调查。1)不同户型对噪声烦扰影响的差异。2)气候对噪声烦扰的影响程度不同。在1045个公寓式住宅对象中收集了603份回复，在独立住宅中收集了712个对象的494个回复。在剂量-反应关系中，尽管气候不同，但独立住宅的非常恼怒百分率大于公寓住宅的非常恼怒百分比。这是因为许多受访者在公寓楼里注意到了附近的噪音，他们可能相对较少感到道路交通噪音比那些住在独立房子里的人更恼人。在噪声烦扰的通径分析中，气候对两地噪声烦扰的直接影响不大。有几个因素对噪声烦恼有很强的直接影响，它们在公寓和独立住宅中普遍存在。认为气候对噪声骚扰没有影响，根据剂量-反应关系和通径分析的结果，目前对独立住宅的调查结果可以适用于公寓住宅。

The social surveys on road traffic noise were carried out for apartment houses and detached houses in colder and warmer areas of Japan for two years in order to clarify two point as follows. 1) The difference of the effect of house type on noise annoyance. 2) The difference of the effect of climate on noise annoyance. 603 responses were collected from 1045 objects in apartment houses and 494 collected from 712 objects in detached houses. It was clear in dose-response relationship that %Very annoyed in detached houses was larger than that in apartment houses in spite of the difference of climate. It's because many respondents noticed neighborhood noises in apartment houses and they might relatively felt road traffic noise less annoyed than those living in detached houses. But there was no difference of the effect to chimate on noise annoyance.In path analysis of noise annoyance, climate had little direct effect on noise annoyance in both areas. Several factors had strong direct effects on noise annoyance and they common to apartment houses and detached houses. It is considered that there is no effect of climate on noise annoyance and the findings in the surveys of detached houses up to the present can be adopted to apartment houses taking account of the results of dose-response relationship and path analysis.
