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

2011年在岘港进行了飞机和道路交通噪声社会调查，2012年在顺化进行了铁路和道路交通噪声社会调查，2013年在阮泰进行了道路交通噪声社会调查。结果获得了足够的数据，绘制了越南飞机和道路交通噪声的典型响应曲线。与欧洲人相比，越南人对飞机噪音的烦恼程度略高，对道路交通噪音的烦恼程度低5- 10分贝。烦恼的患病率在越南的城市中广泛传播，在大城市中发现了更高的烦恼。为了研究城市间的空间差异，采用了结构方程模型。结果发现，居住满意度大大影响噪音烦恼。这表明，不仅要采取有效的噪声防治措施，而且要改善居住环境，才能更好地制定噪声政策。

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.
