Turn Your Head Into Speakers 167
Roland Piquepaille writes "A small company based in Iowa has developed products made with a "smart" metal that can turn your walls or your head into speakers. "Last August, Etrema -- an innovative technology firm nestled in the cornfields of Ames, Iowa -- started selling those chrome discs for $1,500 a pair. Called Whispering Windows, they can turn any wall, window, or drab conference table into a speaker." The author tried the technology, and even if she needed a full bottle of Tylenol after usage, said "it's not every day that your head serves as a piece of stereo equipment." This overview tells you more about this "magic" metal, the Terfenol, which is a combination of terbium and dysprosium. The article also says that we can soon expect pirated versions of Terfenol coming from China."

I seem to recall that SoundBug had poor sound quality because most surfaces and structures have strange acoustic response patterns.
