The overall research investigated intrusive noise levels from construction sites into residential communities which may be detrimental to health. This research used the drone imagery of an actual construction project to identify noise sources from the construction site and CadnaA acoustic software to predict the noise propagation from construction sites in three modelled residential communities. Construction noise propagation and community annoyance were modelled for single-family, multifamily, and high-rise residential neighbourhoods where noise levels exceeded the recommendations of the World Health Organization and Health Canada Guidelines. When construction works continue without any noise mitigation measures, one-fourth of resident would have been overexposed according to the City of Vancouver (CoV) guidelines. Several noise control strategies were applied and finding indicated that a combination of noise controls was more effective than a single control measure. When noise mitigations were in place, the City of Vancouver noise by-laws were found to be attainable, and no residents would have been overexposed to construction noise. However, when applying the Health Canada guidelines, which is more stringent than municipality noise by-laws, it was predicted that more than one-third of residents would be overexposed and would experience widespread annoyance with or without mitigation strategies. The understanding of construction noise from the community perspective in this research provides a new perspective for the study of construction noise that can help regulatory entities to reduce community exposure to construction noise and it offers solutions for construction noise-mitigating strategies to be incorporated into urban planning and public health policy.
