Inverted sound waves can cancel each other in air, I've heard (or not heard) the effect with my own ears.

- TTPrograms 12y agoRight, but for any point source this is effect is going to vary spatially. That's why you can't make one speaker totally cancel out another speaker over a whole room.
- jayd16 12y agoSure, but my point is that there is only one speaker involved so the cancellation happens in the electronics, before any sound is made.
- kordless 12y agoIt's interesting to think of 'cancellation' in different mediums. Waves in physical space. Radio in electromagnetism. And now 'computed' waves cancel each other too.
