How Does a Community Respond to Changes in Aircraft Noise? A Comparison of Two Surveys Conducted 11 Years Apart in Ho Chi Minh City

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.

Models of Aviation Noise Impact in the Context of Operation Decrease at Tan Son Nhat Airport

“…Before the epidemic outbreak, the number of flights operating at the TSN airport had been increasing continuously over the years to meet the growing demand for air travel. Noise exposure around the TSN airport increased from 53 to 71 dB L den (day–evening–night weighted sound pressure level) in 2008 to 63 to 81 dB in 2019 [ 15 ]. Extremely high levels existed in almost all areas in the vicinity of TSN, inside a dense residential area of the most active metropolitan area in Vietnam.…”

A Noise Control Method Using Adaptive Adjustable Parametric Array Loudspeaker to Eliminate Environmental Noise in Real Time

“…Environmental noise is everywhere. However, when people work and live in a high-noise environment for a long time, it brings great risks to people’s health, such as hearing loss and noise trouble [ 1 , 2 ]. As people mainly work and live in indoor environments, the application scenarios of noise control are also mainly aimed at indoor environmental noise.…”
