I’ve got a audio/tech question, maybe someone here might have some insight into.
I’m in need of noise cancellation for various and sundry reasons. i own a pair of BOSE ANC headphones which are tits, but have been looking for a pair of GOOD ANC earbuds that don’t cost $300 bucks, and had an idea that all ANC appears to be, when you break it down, is sound that the earphones/earbuds produce which bounce around in the ear canal and hit the ear drum in certain ways as to “cancel” out various types of background noise.
Again the ANC on my BOSE are amazing. Does anyone know, or have even heard of (no pun intended) anyone who has produced “noise cancelling” sound files?
It seems as if noise cancelling hardware like earphones are producing sounds that cancel out noise, mp3/flac files of “noise cancelling” sound could be on offer somewhere.
Dunno, figured i’d ask. Hope this is the right place to do that, and I’m not breaking any rules, I didn’t know where else to post this.

Yup not possible. Sound is waves. Think of a sine wave that goes up and down. Noise canceling works by canceling the peaks and valleys of a sound wave with inverted valleys and peaks. If the peak is +1 for example, a sound wave with a valley of -1 played at the same time would cancel it out. This is simplistic terms of course.
The sound of your environment is constantly changing. If you wanted a static audio file to cancel out noise you would have to play some customized white noise. Not the effect you’re looking for.
Just extra context. You’ll need ANC buds. Heard Sony is good. Good luck!
