| Research Abstract |
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.
