Silence...

nimrod86

A random idea just popped into my head...

Is it possible to record silence, then play it back really loud through headphones, to cancel out the sound of everything else around you?

eg.

If you were in a loud room, if you play the music loud, you cant hear people over it.

So, if you play the sound of silence really loud, could you make it so you can't hear people like as though loud music was playing?

Would you have to play back the sounds around you out of phase? Or can you use a certain tone in any situation that will cancel all other sound?

No, because the silence in your own room is already loud and it's not blocking out the noise so why would recorded silence.

It's not so silly as you might think. Noise cancellation is difficult, but it's not impossible.

It's already done OP. Sorry about that.

Haha, troll science at its finest. Libraries could start piping silence through a PA systems like supermarkets do music...

Noise calcellation just cuts out lower frequency sounds by means of soundproofing, not by playing silence

and enjoy the silence

silence is the only real language and everything else is a bad translation, its the same as space if you become aware of it you will become aware of a formless and timeless dimension within yourself.
