The impact of confounding factors on moderating short-term responses to noise: A follow-up study conducted at a hospital near Tan Son Nhat Airport

This study explores the intriguing phenomenon of positive participant responses amidst sustained high noise levels in a follow-up survey conducted in the previous year (2023) at Military Hospital 175. Building upon the initial 2022 survey, our investigation reveals a noteworthy continuity of positive responses from participants, despite the persistent influence of high noise levels on both staff and patients. This study, expanding its focus to include road traffic noise surrounding the hospital, highlights the resilience demonstrated by individuals within the hospital environment. The results suggest a complex interplay between perception and adaptation to noise, emphasizing the need for a nuanced understanding of the psychological and physiological responses to sustained high noise levels. This study contributes valuable insights for future interventions and strategies aimed at promoting well-being in healthcare settings with persistent noise challenges.
