Abstract
There have been many arguments about findings of an increase in noise annoyance over time and a recommendation of stricter limits on aircraft noise levels to protect the health of residents around airports. It is crucial to examine if the established exposure–response relationship is suitable for designing future aircraft noise regulations. This study was focused on identifying changes in response to noise over time by comparing community responses from two surveys conducted in 2008 and 2019 at Tân Sơn Nhất (TSN) international airport. Annoyance was found to significantly reduce in 2019 compared to 2008; however, changes in sleep quality were relatively small. Unexpectedly, a gradual increase in the annoyance due to aircraft noise was not found. Results of multiple regression analysis indicated that differences in the reaction of the residents to noise in the two studies were significantly attributed to nonacoustic factors. Noise sensitivity and dissatisfaction with the living environment (e.g., inconvenience in accessing workplace) considerably affect noise annoyance, whereas noise sensitivity, age, and dissatisfaction with the green environment of living areas affect sleep quality. These findings suggest the fulfillment of desired living environment as effective measures for mitigating noise impacts on residents in the vicinity of busy airports.

Recent research on the change caused by the opening of a new terminal building at Noi Bai Airport at the end of 2014 suggests that responses obtained several years later are higher than those obtained before the change occurred under the same noise level
We analyzed the data of 2008 and 2019 aircraft noise surveys in Ho Chi Minh City and compared changes in noise annoyance and sleep quality based on the results of both surveys
Summary
It was decided in the European Ministerial Conference on Environment and Health held in Parma in 2010 to develop new guidelines on noise. These guidelines strongly recommended reducing aircraft noise levels to. European and American studies report that the reaction of people to aircraft noise increases in severity every year [6]. Recent research on the change caused by the opening of a new terminal building at Noi Bai Airport at the end of 2014 suggests that responses obtained several years later are higher than those obtained before the change occurred under the same noise level. The effect due to operational change decreases, as observed in the follow-up study regarding annoyance, but it remains the same
