Anti-teen device not getting banned

my sister and i shared a hearty laugh at my parents who can't hear it. except it hurts our ears. so who is laughing NOW

Genius Juster!

that noise is defiantly ageist, im 25 and it makes my spine hurt i hope they do not use this in americA

Some of the kids at my school use mosquito ringtones instead of silencing or turning off their phones. The teachers can't hear them. I thought it was a pretty spiffy invention (though I'm sure the crowd frequency would hurt a lot), but using it as an "anti-teen" device? That bothers me.

thats similiar to the sounds televisions make, especially tube tv's. i noticed another friend could hear it also, but most don't seem to. I describe it as an ambient high pitched ringing, that seems static like.

"Hi, I'm coming in here to do some quick business and I brought my kid along with me while I drop in. Oh, you say that there is a device that emits a sound that I can't hear but is torturous to my child... Oh well, it will develop character in the long run anyways."

Reality check in the form of a question, WTF? This invention works best under the assumption that all young people are delinquents. However, it sadly punishes all the youth who are not wreckers of havoc. For some reason this strikes me as similar to that behavior chip in the movie "A Clockwork Orange" with the exception that it is not specific to whom it disciplines.

Blatant discrimination. A way to stop this would be to shop where there aren't any of these devices and to get their parents to do the same. Furthermore, even if you're trying to get rid of children and teens from the area, what of those 18+, why should adults still have to deal with that noise, even if it is only for a few years?

That is a horribly annoying sound, its a pulsating pitch of doom! I'm 28 and can still hear it....

Apparently, this audio clip contains the 'mosquito' sound that under-25s can hear. I can only hear some people milling laughing and somebody hammering for a bit though. Can anyone hear this?

I'd imagine it sounds like this irritating squeak, which I can definitely hear:
