Abstract Noise is a pervasive environmental stressor that has adverse impacts on people's mental health. However, past studies on the relationship between individuals' chronic noise exposure and psychological stress were inconclusive, partly due to their ignorance of the role of individual mobility and the temporality of the exposure-effect relationship. This study examines how individual mobility and temporality influence the relationship between noise exposure, noise annoyance, and psychological stress. An approach combining geographic ecological momentary assessment (GEMA) and portable noise sensors is used to collect real-time data from a sample of residents in Beijing, China. Using structural equation modeling, the study found that noise annoyance mediates the association between noise exposure and psychological stress in real-time. Further, participants reported divergent psychological stress levels in locations other than their residences and workplaces. Compared with the home locations, recreational and commercial places are noisier but less stressful, while participants tend to experience higher levels of noise and annoyance during travel. In addition, the cumulative effect of noise exposure on stress decreases in magnitude over time but stays significant within 3 h of the exposure. The results suggest that health impact assessments should take into account people's real-time noise exposure and psychological responses to noise.
