Addicted2ColdTurkey Posted May 24, 2011 Share Posted May 24, 2011 I did some research on this project, and it does not seem that there is a program that can actively receive sound and then find the inverse of that wave and play it out. On a level of 1 to 10 how difficult would a project like this be programming wise? In theory it seems pretty easy. Link to comment Share on other sites More sharing options...
TonyMcC Posted May 24, 2011 Share Posted May 24, 2011 I believe some cars have active noise cancellation. If you google - cars active noise cancellation - you will get quite a lot of information. Off the top of my head I would suggest that one problem would be the ,admittedly short, time needed to process the unwanted noise and output the same in anti-phase.
