Living Room / IDEA: cancel elevator music
« on: July 26, 2011, 03:36 AM »
Lately, (perhaps because my hearing is going a bit with age), I've become increasingly wishing the ubiquitous music played in stores would just go away. And I have an idea that perhaps it's possible.
I am not a tech on how noise cancelling headphones work, but I understand they read the ambient noise and find frequency patterns associated with background that they can generate cancelling waves for. I've also heard that there are now programs that can identify a song from a clip. So why not have your cell phone listen to the music, identify it, and send cancelling waves to your ears?
Heck, there might even be a commercial product there if the project is too big for a volunteer effort. And given the difficulty my wife is now experiencing in hearing, this is a growing problem as the population ages that might even attract development funds from those concerned with those suffering hearing disability.
Have fun with this.
