Effects of personal noise exposure, sleep quality, and burnout on quality of life: An online participation cohort study in Taiwan.

Chronic noise exposure in daily life not only causes physical and mental illness but also reduces quality of life. However, collecting objective data on sound exposure and subjective acoustic comfort through a traditional one-shot survey is difficult. This study applied online chatbots in social media to explore the effects of daily sound exposure, personal characteristics, noise sensitivity, burnout status, and sleep quality on quality of life using a short-term participatory cohort design. During the two-month survey in 2022, 207 participants completed at least 15 days of collection of data on sound exposure and perception, as well as periodic structural questionnaires during the follow-ups. Linear regression and generalized linear models were applied to explore the factors influencing personal burnout, the Pittsburgh Sleep Quality Index, and quality of life. A chain mediation model was applied to explore the direct and indirect effects of noise exposure on quality of life. The results showed a better quality of life among respondents who rated their home environment better, were in good health, had better daily acoustic comfort, and were less exposed to noise during the week. In contrast, respondents with lower daily acoustic comfort and a higher frequency of noise-induced sleep disturbances and mood disorders were more likely to have poorer sleep quality. A higher personal burnout was associated with poorer health, longer exposure to noise during the week, a higher frequency of noise-induced illnesses, and neurotic traits. In the mediation analyses, noise-induced sleep disturbance and better daily acoustic comfort also had important direct influences on quality of life compared to the indirect pathway through sleep quality and personal burnout. In conclusion, noise exposure in daily life not only exacerbated poor sleep quality and personal burnout but also reduced quality of life.
