摘要

Social surveys on community response to road traffic noise have been performed since 2005 in five major cities in Vietnam: Hanoi, Ho Chi Minh City, Da Nang, Hue and Thai Nguyen. The total sample size and the average response rate were 4966 and 64%, respectively. The noise exposures ranged from 61 to 83 dB in L_(den). The exposure-response relationship was drawn with logistic regression curve based on all the socio-acoustic survey data, which can be proposed as the representative exposure-response relationship for road traffic noise in Vietnam. This curve showed that Vietnamese respondents were about 5 to 10 dB less annoyed by road traffic noise than those of EU and Japan. Exposure-response curves for general annoyance, awaking, falling asleep, conversation, telephone-listening, TV/Radio listening, reading/thinking, and rest disturbances were also drawn. Annoyance in the two largest cities, Hanoi and Ho Chi Minh City, were higher than those in the other three cities. Sleep disturbance was severer than listening and the other activity disturbances in all the cities. The distribution pattern of annoyance was consistent with those of environmental factors such as residential satisfaction. This finding suggests that noise annoyance is strongly affected by or interacted with the evaluation of residential environment.
