still got it?
So, there's this high pitched noise that sounds like a mosquito and only kids can hear it. only because your hearing declines as you get older and blah blah. It was originally used to keep kids out of nice stores, but the kids caught on and turned it into a cell phone ring tone. Now kids can keep their cell phones on during class, because the teachers can't hear it.
here's an article that goes in depth and also has a link to the sound, so you can hear if you're old or not.
I heard it. phewph.
