Picture-Frustration Test to Assess Environmental Attitudes of Residents Exposed to Aircraft Noise from Hanoi Noi Bai International Airport

Abstract

Expanding transport systems for life convenience and preserving the natural environment are essential but conflicting human activities. The operational expansion after the opening of a new terminal building at Hanoi Noi Bai International Airport was followed by changes in aircraft noise exposure. A series of socio-acoustic surveys were conducted around the airport, revealing different levels of noise annoyance responses in the surveyed sites. To clarify this discrepancy and to explore people’s true feelings, the Picture-Frustration test was conducted to assess attitudes toward the airport, aircraft noise, living environment, and awareness of environmental protection in the communities around the airport. A total of 321 responses were obtained. The results showed a significant variation in attitudes toward the airport and natural environment among residents in different areas. Urban residents preferred natural environment more than those living in rural and mixed sites, who desired harmony between nature and life convenience. Residents in rural sites raised more complaints about aircraft noise effects on sleep than those in the other sites. Factors of occupations and gardening activities did not affect residents’ attitudes toward the airport. The attitudes of the participants varied depending on the exposure noise levels. It was suggested that using multiple questioning methods is necessary to certify the true opinions and aspirations of people living in the project area and ensure sustainable development.
