A Cell Phone Ring Tone Only Kids Can Hear

This made the rounds not to long ago. While the technology is real, it's called Mosquito, the part about using it as a ring-tone is not true. The problem is that current cellphones can not produce the high pitched tones that make up the audible part of the youth deterrent.

Calling it a hoax without doing some simple research is a very lazy statement. Lots of cell phones these days have speakers built into the side of the case. The quality is far from perfect but they have no problem generating high pitched frequencies. Out of curiosity I recorded a 10KHz to 20KHz sine sweep and played it back through my phone while checking it with a real time analyzer. My phone starts to roll off around 16.5KHz and is barely audible at 18KHz. The problem with the high frequency ring tone is if you are in a large group of people, it is very difficult to distinguish which phone is actually ringing.

It's not a hoax. I can use it on a phone, and my parents, and others older than around lets say.. 25.. Cant hear it at all.. A phone can do it, it's already been proven. So looks like you need to do research first, because cant just decide a phone can't do that.

I can hear it just fine and I'm 27.

I also can hear it and I'm 54!

where can you here te ringtone i heard it from a friend on the bus.
