According to an article in Information Week, earbud headphones, the type that rest inside the ear, can lead to permanent damage after just an hour of high-volume music in the 110-120 decibel range. Supposedly, podcasts are compounding the problem, because people are using the devices longer than they used CD players or Walkmans in the past.

The article recommends “listening no more than an hour a day, switching to over-the-ear headphones, and dialing down the volume on iPods to 6 or lower.”
