My daughter just clued me into the latest scheme by teenagers to put one over on the grown ups: The Mosquito Ring Tone. (LINK
)
My daughter's friends are all setting their phones to use the tone for texting. That way they can leave their phones on in their classes and know when they've received a message.
It exploits the effect that age has on your hearing. As we get older, we lose the ability to hear very high frequencies. I'm lucky that at 43, I can still hear the tone.
I downloaded the MP3 file from the link above. I played it for the office. Only one person could hear it faintly when I had the speakers at full volume. For me, the sound was cutting through my teeth fillings.
Go to the link and play the sound for yourself. Tell me if you can hear the tone. If you're not shy, include your age.
I'd like to be the Cool Dad and not forward this info to my daughter's high school administration, but shouldn't they be learning instead of texting during class?

You can hear the desks vibrate every two seconds.
