Health impact of noise in the Paris agglomeration: assessment of healthy life years lost

摘要

Many studies have shown that environmental noise exposures are related to non-auditory effects such as sleep disturbance, annoyance and cardiovascular diseases. The Regional Health Observatory and Bruitparif applied WHO methodology in order to quantify impacts of environmental noise on the health of the population in the Paris metropolitan area, in terms of DALYs (disability-adjusted life-years). Health and noise exposure (coming from the strategic noise maps) data were aggregated at the "commune" (French counties) level. Our evaluation showed that around 66,000 healthy life years were lost every year in the Paris agglomeration due to noise exposure. The main health outcomes were sleep disturbance (nearly two thirds of the years lost) and annoyance. Traffic noise had the greatest health impact (about 87% of the DALYs loss). Health impacts related to aircraft noise were much lower (4% of the DALYs loss), but they should be taken cautiously, as the use of the Lden indicator appears inaccurate to account for the event nature of aircraft noise. This assessment gives a minimum approach of the health impact of noise in the Paris agglomeration and points that noise is a main public health interest. The results of this study will be presented.
