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.

thanks, i use earplugs all the way up in there, and they block pretty much everything except movement, which isn't sound per se, but it is vibration, and that seems to be silenced by my QCII headphones which I've been wearing to bed for a while now, they block pretty much everything and I'm not woken up by my upstairs neighbors walking abound on their floor/my ceiling like i am when i've got ear plug in. iv'e tried the bose qcii earbuds and the sony 1000xm4, and in my experience neither of them hold a candle to my bose qcii over the ear headphones in carpetting of sound. i figured if there was a general "sound cancelling" frequency someone somewhere at sometime might have recorded it as a mp3 or flac and i could try to play it from any old earbuds whilst i slept, but it seems that's not technically how noise cancellation functions, but i do appreciate your response, being an expert, thanks again

Im wondering if the passive attenuation of your headphones is doing more work than the ANR system is? Regardless sound is perception and that's all that matters. I think using any ear bud, headphone or even a speaker with Brown Noise playing loudly is likely the only sure way to completely block out your perception of all noise. Or just take some gummies and turn your brain off :)
