(CTV.CA) — A new U.S. study looking at pedestrians who were killed or injured while wearing headphones finds that the incidents appear to be on the rise.

The study’s lead author, Dr. Richard Lichenstein, says he began the research after hearing of a local teen who died while crossing railroad tracks. The teen was wearing headphones and didn’t hear the oncoming train, even though it blasted its horn before hitting the boy.

“As a pediatric emergency physician and someone interested in safety and prevention, I saw this as an opportunity to — at minimum — alert parents of teens and young adults of the potential risk of wearing headphones where moving vehicles are present,” Lichenstein said.
