Excess noise can lead to physiological stress responses in the body that many contribute to the development of cardiovascular-related health issues. Noise at night may also disrupt sleep, which can be a risk factor for a number of chronic diseases.
Evaluate the impact of traffic-related noise on the development of chronic diseases
Investigate potential interactions between noise and other harmful environmental risk factors, such as air pollution, on human health
Spatial variations in traffic-related noise in the city of Toronto, Ontario were derived using exposure surfaces developed from continuous measures of noise from population-based surveys conducted in 2012-20131.
ONPHEC studies that have assessed the effects of noise on chronic disease include:
