Community response to aircraft noise in Ho Chi Minh City and Hanoi

摘要

To formulate Vietnamese and global noise policies, social surveys on community response to aircraft noise and combined noise from aircraft and road traffic were carried out in Ho Chi Minh City from August to September 2008 and in Hanoi from August to September 2009. In total, 1562 and 1397 responses were obtained in Ho Chi Minh City and Hanoi, respectively. The aircraft noise was measured for seven successive days, and the combined noise was measured fer 24 h. Aircraft and combined noise exposures ranged from 53 to 71 dB and 73 to 83 dB L_(den) in Ho Chi Minh City and from 48 to 61 dB and 70 to 82 dB L_(dCn) in Hanoi, respectively. The dose-response curve for aircraft noise for Vietnam was established and fitted onto the curve for the European Union. For the same noise exposure, the aircraft noise annoyance in Hanoi was higher than that in Ho Chi Minh City because of the lower background noise level in Hanoi.
