The data from aircraft and road traffic noise surveys conducted in Hanoi and Ho Chi Minh City were re-analyzed to investigate whether residential and environmental factors influence noise annoyance and activity disturbances. The multiple logistic regression analysis was applied with personal and residential environmental factors such as age, gender, satisfaction with residential area, comfort in rainy season, greenery in residential area, quietness of residential area, and so on as the independent variables and noise annoyance as the dependent variable. The results showed that annoyance caused by road traffic was significantly affected by the satisfaction with residential area, the comfort in rainy season and quietness of residential area, while aircraft noise annoyance wasn’t significantly influenced by these variables except the satisfaction withthe residential area. The quality of sleep was affected by the satisfaction withthe residential area and the presence of greenery with the areas along the roads but was not affected in areas exposed by aircraft noise. In areas with combined noises, the satisfaction withthe residential area affected the quality of sleep of the residents.
