Wait are you sure they're just playing a sound that everyone can hear? lol I'd heard about these sounds only teengaers can hear and thought only special devices could produce this noise (ie not normal speakers on our computers)? I could be wrong though....
Can you hear this?
Im 31 I just heard a long beep type noise
Well I am a teenager and I can hear it.
Though it got more quiet towards the end.
