New Tech to Help Prevent Hearing Loss?

Wired is reporting that Blomberg is working on an invention to help users maintain a greater control over the volume output of portable music devices. Many people have expressed a growing concern about hearing loss in recent years due to the increased use of headphones and exposure to loud music. From the article: "Les Blomberg, executive director of the Noise Pollution Clearinghouse, described hearing loss with a nice analogy: 'If you have a field of grass and you walk on it, you compress the grass and it bends down over the night, and in a few days, it springs back up and is OK again. But if you keep doing that over and over, you wear a path in it. And that's kind of what happens with hearing loss.'"
