Road Traffic Noise, Noise Difference Between Residential Facades, and Risk of Parkinson Disease

Is long-term exposure to road traffic noise associated with a higher risk of Parkinson disease? In this cohort study including over 3 million participants, long-term exposure to road traffic noise was associated with a higher risk of Parkinson disease. Having a quiet facade appeared to attenuate the association between noise and risk of Parkinson disease. These findings suggest that road traffic noise may be a risk factor for Parkinson disease and that access to a quiet facade may mitigate the associated risk.
