I tested it out, and my parents couldn't hear it. :p

Go to the site below and it should starting playing.
Go ask your parents if they can hear it, and tell the reactions.

Have this as your ringtone so the teachers don't hear it. :carling:

I have an app like this on my iPhone called "Dog Whistle". :y:

So old .

LMAO. I'ma set that as my ringtone in class and test it out :carling:

That's weird, I hear this same sound coming from my mom's room all the time O.o.

That thing is so ****ing annoying; couple of years ago everyone had that and would never answer their phones> But I guess it works since the teacher never said anything.

Hah this is my text alert tone =D
