iPods and Hearing Loss

iPod’s Popular Earbuds: Hip Or Harmful? is one of a number of articles on hearng loss and iPods. The problem is the length of time people listen to iPods (they last longer than earlier devices like the Walkman), the lack of distortion at the high range (analogue devices would distort at the high end), and the bud-type earphones that further raise the volume. In Europe the iPods are sold with the a lower maximum volume for these reasons. See also Macworld UK – Experts warn of iPod hearing loss.

I’ve found myself listending at almost full volume, especially in noisy situations where I want drown out sound. Hmmm …. What did you say? Speak up.

Greasemonky: messing with web pages

Thanks to Matt Patey who pointed me to Greasemonkey which offers a Firefox extension that allows you control aspects of page’s design using DHTML.

The underlying technology is called Anoto and it is also being used in products like LeapFrog’s FLY pentop computer for kids. Fly lets kids draw out a piano keyboard and then lets you play the piano by pressing the pen to the keys. A sound synthesizer plays the note.
Such pen and voice systems suggest a whole new type of interface that is not screen or touch pad based. You could have a pen shaped phone where you just write the phone number down and it calls it. The trick is the paper that lets it tack its absolute position even if you raise the pen and move it. I’m sure we are going to see innovative uses for this technology that take advantage of what you can do when you don’t need a screen.
