In what is considered a significant development towards rebuilding broken bones,Aussie scientists have developed a synthetic biomaterial which helps the body create a bone on its own.

The study on the iPod-listening-generation also showed that teen boys listen louder than teen girls.

And CU-Boulder audiologist and doctoral candidate Cory Portnuff, who headed the study, said that teens who express the most concern about the risk for and severity of hearing loss from iPods actually play their music at higher levels than their peers.

He said that such behaviours put teens at an increased risk of music-induced hearing loss.

Also, the study indicated that teens play their music louder than young adults, and teens may inaccurately perceive how loud they are playing their music.

However, Portnuff said that the good news is that teens in the study who understand the benefits of listening at a lower volume have less of a risk for hearing loss.

"We really don't a have good explanation for why teens concerned about the hearing loss risk actually play their music louder than others. But we do know that teens who knew what the benefits were of listening at lower levels had less hearing loss risk, which is why we believe targeted education is the key," he said.

He further added that the new study indicated a relatively small percentage of teens, somewhere between 7 and 24 percent, listen to their iPods and MP3 players at risky levels.

"We don't seem to be at an epidemic level for hearing loss from music players," said Portnuff.

In a 2006 study, researchers indicated that a typical person can safely listen to an iPod for 4.6 hours per day at 70 percent volume using stock earphones.

But listening to music at full volume for more than five minutes a day using stock earphones increased the risk of hearing loss in a typical person, according to the study.

The results of the study were presented at the annual Hearing Conservation Conference held in Atlanta last week.
