How noise canceling headphones work

Was looking around and found this nice explanation of how noise canceling works on headphones and figured it would be a good one to share here with everyone,

If you have any questions about it let me know.
Happy reading!

First they hear the sound. Then they play a sound that is the opposite of that sound, timed perfectly to reach your ears at the same time, so that your ear hears the sum of those two sounds - that is, nothing.

Easy, except for all the math and engineering to make it work correctly. :slight_smile:

It’s fine until you have to figure it out yourself :joy: but those are small details anyway

You guys ruined NC for me now. I thought they put little noise fairies in the earbuds with magical sound blocking unicorn shields. Lol. :wink:

That is the very technical terminology for it yes but I didn’t want to confuse people who weren’t on that level yet😂
