In ‚Dying for some quiet: The truth about noise pollution‚ in the NewScientist they state that
«…the WHO’s findings suggest that long-term exposure to traffic noise may account for 3 per cent of deaths from ischaemic heart disease in Europe – typically heart attacks.»
In Europa alone probably half a million lifeyears are lost anually.
Nothing new are the facts that chronical niose pollution cause sleep disorder, hardness of hearing and learning disorders.

Problem solved, you think? Wait until 12:02…
