I have an audiologist friend at Wichita State University who actually pulls off earphones of students he sees and, in the interest of science, asks if he can measure the output of the signal going into their heads.

Unfortunately, the ear buds are even more likely to cause hearing loss than the muff-type earphones that were used on Walkman and portable CD players.

We're seeing the kind of hearing loss in younger people typically found in aging adults. Unfortunately, the ear buds preferred by music listeners are even more likely to cause hearing loss than the muff-type earphones that were associated with the older devices.

I have an audiologist friend at Wichita (Kan.) State University who actually pulls off earphones of students he sees and asks, in the interest of science, if he could measure the output of the signal going into their heads.

The combination of high-signal intensity and long listening duration is a proven formula for permanent, irreversible hearing loss.

That's the difference in intensity between the sound made by a vacuum cleaner and the sound of a motorcycle engine.

That's a sound level that's equivalent to the measures that are made at rock concerts. And it's enough to cause hearing loss after only about an hour and 15 minutes.

If music listeners are willing to turn the volume down further still and use different headphones, they can increase the amount of time that they can safely listen.

I have an audiologist friend at Wichita State University who actually pulls off earphones of students he sees and, in the interest of science, asks if he can measure the output of the signal going into their heads. Commodore 64 er computeren, der lokker til demo-programmering. He found that often students were listening at 110 to 120 decibels.

Insert earphones can boost the signal by as much as six to nine decibels. That's about the difference between the sound of a vacuum cleaner and a motorcycle. It's a significant difference.
