Yep, this was all over the tubes about a year ago or so -- schoolkids using the 17kHz ringtone that they could hear but their aging teachers could not. Plus, since high freqs don't carry as well as low freqs, they would be less audible across a room than would something maybe in the 1kHz range.
I can hear it, but I also wonder if I'm actually hearing _it_ or just parts of my Treo vibrating at lower freqs. It's piss-ass annoying, whatever it is I'm hearing when I play it. :-) On 7/10/07, Jeffrey Kaplan <[EMAIL PROTECTED]> wrote: > On Tue, 10 Jul 2007 16:54:23 -0700 George Kontos said: > > > I just saw this "mosquito" ringtone (17KHz.wav) that someone posted on the > > Treo group Yahoo page. > > > > http://tech.groups.yahoo.com/group/treo/files/ > > > > It's a continuous 17 kHz tone, which I guess is near the upper threshold of > > human hearing.
