Can you hear it?

This is a hearing test, this sound is apparantly used in the US to stop kids hanging around outside shops, apparantly anyone over 20 cant hear it. Im 22 and I can hear it and another guy sat near me can hear it and he's over 40, can any of you not hear it?!

Yes Andy I can hear it and I am a lot over 40!

Couldn't hear it at first because I had the sound switched off

 

I think they've got the wrong noise there, it nearly blew the cones out of my speakers.

 

Yes I can hear it too and I'm quite old!!

 

Thought so, ah the idiots on youtube that think they know it all!

 

Yes Andy I am 50 and that is so bloody anoying

I had the sound turned up full-blast because I thought it would be a really quiet sound but it wasn't. Yes, I could hear it!
