TL;DR: In this article, structural equation models were developed by linking questionnaire items from the socio-acoustic surveys on road traffic and aircraft noise annoyance, indicating that sensitivity and satisfaction with the living environment were the main modifiers of noise annoyance in Vietnam.
Abstract: Socio-acoustic surveys on the community response to transportation noise were carried out in five Vietnamese cities from 2005 to 2013. Approximately 9900 responses were obtained from these surveys. Variations in exposureâ–“response curves were found among different regions and noise sources. Various degrees of annoyance resulting from the same noise exposure implied the effects of non-acoustic factors, such as urban lifestyles and attitudes towards noise sources. To assess these effects, structural equation models were developed in this study by linking questionnaire items from the socio-acoustic surveys on road traffic and aircraft noise annoyance. The sample sizes were 3783 and 1973 for road traffic and aircraft noise surveys, respectively; therefore, they were sufficiently large to estimate and compare the models among cities and between two types of noise source. The final model included three latent factors: sensitivity, activity interference, and satisfaction with the living environment. Sensitivity to noise, vibration, and heat were determinants of personal sensitivity. Activity interference was measured by awakening during sleep, rest, and listening disturbances. The quietness of living areas, preference for living areas, and comfort during the dry season were used to determine satisfaction with the living environment. A good model fit was observed, indicating that sensitivity and satisfaction with the living environment were the main modifiers of noise annoyance in Vietnam. The findings of this study suggest measures for reducing noise annoyance among urban residents in Vietnam.

TL;DR: Wang et al. as mentioned in this paper conducted a social survey on community response to high-speed railway noise in Tianjin, China, from March 2018 to March 2019, and found that the proportion of Chinese residents with high noise annoyance and activity interference increased exponentially with the increase of high speed railway noise levels.

TL;DR: Non-acoustic factors such as noise sensitivity, sound insulation capacity of houses, and length of residence were found to curb the respondents’ annoyance, insomnia, and high blood pressure, and an improvement in residence quality and a restriction on nighttime flight operation is necessitated.
Abstract: Herein, the effects of changes in acoustic and non-acoustic factors on public health and reactions were assessed using two follow-up investigations; this was achieved after three surveys were conducted on the impact of the step change in noise caused by the increased number of flights at the Noi Bai International Airport in Hanoi (Vietnam) after the new terminal building was opened to the public. Exposure-response relationships established in the follow-up studies were less in number than those established in 2015 after the step change had occurred, and were almost similar to the relationship established in the survey conducted before the step change; however, these relationships were significantly greater than those established in the European Union position paper. Comparisons between respondents with high blood pressure and insomnia ratios at different noise level ranges showed that there is no significant association between ratios of high blood pressure and day-evening-night noise levels; however, an exposure-response relationship was discovered between insomnia and night-time noise levels. Non-acoustic factors such as noise sensitivity, sound insulation capacity of houses, and length of residence were found to curb the respondents' annoyance, insomnia, and high blood pressure. Thus, an improvement in residence quality and a restriction on nighttime flight operation is necessitated.
