That’s definitely wrong. You should follow danielle’s mastodon, she’s working on elementary all the time.

Even half an hour next to the PA without special ear plugs is enough to permanently harm your hearing.

Seriously, stop being an asshole. Coil whine is a well-documented behaviour that creates a loud, high pitched noise.

As coil whine is at the very limit of what human hearing can accomplish, it doesn’t take much until you’re unable to hear it. So you’re likely too old or went to too many concerts to be able to hear it.

Good ears? the question is when, not where, and the answer is half a lifetime ago.
