Sound deterrent being used to keep young people out of places

15 kHz sine wave frequency
I’ve read that businesses, parks, and other locations are using these high frequency sound deterrents to repel young people at times when they are not supposed to be there. Apparently, the frequency being used is in the YouTube link above. I’m 52, and I can’t hear a thing. I’ve seen younger people post that it’s anything from uncomfortable to ear-splitting. What do you hear?

Job application's have the same response, also less annoying to those working in the area.

That's really uncomfortable.

Phones and cheap speakers don't carry higher frequencies well, so it may be because of that. Try using headphones.

Classic stupid backwards american policy to try to keep people out of parks at certain times when in other countries they can thrive 24/7

It sounds like the noise they play on TV before a weather update or something....

If you don't the pervs and gays will take them over and make the park into their own little play land.

I heard it on my phone. Had to put it up to my ear though.

I hear nothing.
It bothers my face, ears, jaw and upper rear cranium, however.

I hear it but it doesn’t bother me. Does that mean I’m only sort of old?
