The former, I'd think. For that to work on the room level, you'd need to have sensors surrounding the room and speakers in all the walls. Sound waves inside a room aren't uniform enough for the a simple speaker setup to cancel them out. You've probably noticed how the way a room sounds can change substantially just from turning your head or shifting it a few inches one way or the other? The same would be true with a microphone assembly that you tried to use for noise cancellation. And if the noise cancellation weren't calibrated correctly, you'd wind up with spots that were noisier than they'd be without the setup. Really this is a job best suited to headphones. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
