Annoyance, sleep and concentration problems due to combined traffic noise and the benefit of quiet side
Bodin et al. (2015) conducted a survey among 2,612 individuals, with questions on the outdoor environment, noise sensitivity, noise annoyance, sleep quality, and concentration problems. The results of the study revealed that individuals with access to quiet places reported a reduced risk of annoyance and concentration problems. In contrast, individuals living in populated regions reported poor sleep quality and concentration problems. From the study, it could be concluded that a reduction in concentration and education attainment is associated with road traffic noise, as these noise levels are high enough to result in a lack of focus and concentration.
