Construction noise annoyance and its evolution: Insights from the Turcot Project longitudinal study.

This study examined how construction noise levels and associated annoyance evolved over 4 years during the rehabilitation work of a metropolitan highway interchange. A total of 1409 participants, grouped by their proximity to the construction sites, completed a socio-acoustic survey on their personal situation and noise perception. Noise levels were monitored using 18 autonomous stations near the construction sites. Findings showed that a significant portion of participants experienced annoyance due to construction noise, though annoyance levels decreased significantly over time in both groups. Interestingly, those living closer to the construction sites reported a faster decline in overall construction noise annoyance and annoyance from other aspects of the work undertaken. Regression models indicated that construction noise levels explained only a small portion of annoyance variance. Key contributing factors included annoyance from other construction nuisances, noise perception in the bedroom, and perceived safety. This study provides valuable insights for future development of policy concerning noise on construction sites. Specifically, the results suggest that taking into account identified socio-demographic, psychosocial, and contextual variables, as well as the individuals' perception of noise levels and construction-related nuisances, could help to reduce construction noise annoyance, ultimately improving the quality of life for nearby residents.
