This is correct. I'm baffled by the amount of people making false claims as to the efficacy of noise cancelling headphones. Why are so many people pulling that shit straight out of their ass?

Noise cancelling headphones use destructive interference. Essentially, they play sounds that are designed to bring high pressure to your ears when the sound they're trying to cancel is bringing low pressure and vice versa, so the sum of air pressures adds up to something closer to a normal atmospheric pressure and the sound is quieter overall. In order to do that, it needs to be able to at least kind of guess what sounds will play when.

Cause they are entitled parents that think just because they can content with their own child, everyone else around them should too.

It is not like they are the ones using noise cancelling headphones in planes.

Hey dipshit. Why do you feel entitled to be in public when your redditor neckbeard stench permeates the entire area around you? Why do you feel entitled to be alive when the natural response to psychopaths like you who can not even muster some empathy for literal babies is to put you down?
