I have often wondered if the ANC creates more noise in overcoming the outside noise. I did some googling, but the results made me feel like I was asking a dumb question. I'm genuinely curious: are there any audiophiles on here that could answer? FWIW - with the ANC off, sounds that make me 'cringe' (sawzall, table saw, hammer drill, etc.) are very much muffled and seem to be just as muffled as when using foam ear plugs. As others have said, there is a big difference between noise levels for a guy remodeling his bathroom with power tools and a someone that saws concrete for a living.

Not a dumb question at all! At a basic level, ANC creates "anti-noise", a waveform 180º out of phase with the noise, and they cancel each other out. So the resulting waveform is much lower amplitude than the original. I don't know anything about this channel but I watched a bit of this video and it seems to be a good explanation of how it works: https://www.youtube.com/watch?v=6GC4P5r7Zaw https://www.youtube.com/watch?v=6GC4P5r7Zaw
