Re: Personal Audio Space?

["Luden" <luden21@mediaone.net>]

I've heard of a company in Cambridge, Ma. that is working on a device
that will sample the surrounding noise and play it back 180 degrees out
of phase. They claim that it will cancel out about 97% of the noise now
and they are working on 100% which they claim is possible. I can't re-
member the name of the company but I saw the article on Boston.com
