Thanks babe for this I’ve had a bunch of fun with it.  I played it and I had to turn it up really high to hear it, meanwhile all my students are like “Ahhhh!!!! What’s that noise!?”  *giggle*

Teens Turn ‘Repeller’ into Adult-Proof Ringtone

At issue is a text-message ringtone that emits the same pitch as the Mosquito. Using it, students can learn about a new message while they’re in class — where they’re not supposed to be using their cellphones. Most of their teachers can’t hear the alert.
