Healthy Life Years Lost
1 million to 1.6 million healthy life years are lost from traffic-related noise every year in western Europe.
(This is a measure of actual life years lost, combined with years lived with disability, which are weighted for diminished quality of life. Also known as DALYs (Disability-Adjusted Life Years).)
