Headphones drown out sound of danger

Members of the iPod Generation face a new health risk – they are increasingly caught up in vehicle accidents while listening to headphones, according to new research.

A US study shows that the number of deaths or injuries to pedestrians who are wearing headphones at the time of a vehicle accident has tripled over the past six years.

Researchers identified just 16 cases in 2004-5, but by 2010-2011 this had reached 47.
