NEW YORK (Reuters Health) - Blasting music can be hard on the ears and the neighbors, and now researchers say it can also pack enough punch to collapse a lung.

Reporting in the medical journal Thorax, they describe the cases of four young men who suffered a lung collapse -- technically called pneumothorax --that appeared to be triggered by loud music. Three of the men were at a concert or club when the pneumothorax occurred, while the fourth was in his car, which was outfitted with a 1,000-watt bass box because he "liked to listen to loud music."
