To calculate the number of avoidable deaths, the study uses city-specific data on mortality from Ischaemic Heart Disease (IHD) causes for 2015 from the Eurostat database and applies the most recent and robust scientific evidence on the relationship between road traffic noise levels and mortality from IHD. The study follows a comparative risk assessment approach by comparing current population exposure to road traffic noise to a theoretical reduction to WHO recommended levels. The number of avoidable deaths is estimated as a function of these reductions and the scientific evidence on the relationship between road traffic noise and mortality from IHD.
