Bravo and on point - there is no such thing as silence.
If you listen very hard the quiter it gets the louder it gets in your head. its true.

This is really helpful and informative thanks for making this!

[@amypandolfi5888]

Fascinating!

[@schylur]

nice explanation this will help a lot editing videos subscribed 👍

[@henryssurfshowcase]

Good one thanks, seems like listening to those generated tones can hurt your ears, even if you don’t hear them?..

[@DotDotMatrix]

Maybe if it’s really really loud… but then you would be concerned about more than your ears, which is the goal of sonic weapons, but they seem to be impractical in most situations… unless the point is to get someone annoyed enough to go away.

[@adamdanial9420]

So we cannot hear hi res audio right?

[@DotDotMatrix]

UA-cam audio starts to taper off somewhere around 15-18k but that also depends on the quality setting of the video. 360p videos have more audio compression than 1080HD videos. I think it ranges from 96kbps to 128kbps AAC codec in most cases.

My computer speakers emit 100 to 10,000... And I thought I had really good speakers for a computer, ha!

Me on my shitty Motorola earphones: hmmm yes interesting
