Comment on What is the absolute max level of ear protection you can get?
HelixDab2@lemm.ee 5 months agoANC isn’t protective in any way. If anything it’s probably just as damaging.
That’s just not true.
Your ear largely hears things through changes in air pressure. Projecting the same frequency and amplitude at the opposite phase prevents the change in air pressure in the first place. It’s literally cancelling the sound.

You’re so wrong about this. ANC pretty much eliminates pressure inside the ear canal. That’s how ANC works. No pressure waves, no sound, no damage.

You’re not adding more pressure anywhere; you’re cancelling that pressure out.

Except that’s exactly how nose canceling ear phones work. It’s not like that have an external speaker projecting sound 🤦🏼♂️

Mine work like this: “Got your nose. Neener neener neener.”

Bro. It’s not “just more pressure.” It’s literally less pressure.
If there are water waves moving a boat up and down, and you actively apply some movement (ha! pressure!) to the water so you generate waves that cancel the existing ones so that the boat stands still, would you say “but you don’t understand, the is getting MORE PRESSURE!!! It’s being damaged!!!”? Of course not. It’s pretty much the same principle.
Get a highschool physics book, read the chapter about sound, and come back. Otherwise, just stop.
