Social surveys on commnity response to transportation noises in middle-sized cities of Vietnam and construction of Asian Socio-Acoustic Survey Data Archive

2011年对岘港市的飞机和道路交通噪声进行社会调查，2012年对顺化市的铁路和道路交通噪声进行社会调查，对太原市的道路交通噪声进行社会调查。因此，获得了足够的数据来绘制越南飞机和道路交通噪声的代表性暴露反应曲线。与欧洲人相比，越南人对飞机噪音的厌烦程度略高，对道路交通噪音的厌烦程度则低5-10分贝。越南的城市普遍存在烦恼，大城市的烦恼程度更高。为了研究不同城市之间的恼人程度差异，我们采用了结构方程模型。研究发现，居住满意度对噪声干扰有较大影响。由此可见，制定完善的噪声政策，不仅要采取有效的噪声对策，而且要改善居住环境。

Social surveys on aircraft and road traffic noises in Da Nang in 2011, those on railway and road traffic noises in Hue in 2012 and that on road traffic noise in Thai Nguyen were carried out. As a result enough data were obtained to draw the representative exposure-reponse curves for aircraft and road traffic noises in Vietnam. Vietnamese people were slightly more annoyed by aircraft noise and 5-10dB less annoyed by road traffic noise than European people. Prevalence of annoyance was widely spread among cities of Vietanam and higher annoyance was found in larger cities. To investigate why annoyace was so different among cities, structural equation model was applied. It was found that residence satisfaction greatly affected noise annoyance. This suggests that not only effective noise countermeasures but also improvement of residential environment are of importance for the better noise policies.
