CNN had a piece on special ring tones only
teens can hear. Couldn't find link to said. Uses
very high frequencies most adults are unaware
of. Would allow teens to receive calls in the
school class room. I guess only other teens
would find it distracting in doing so.

I can hear it clearly on the Grados, but not on speakers in the computer
room.

CNN was full of ****. No phone has the frequency response.
The CNN reporter probably has never heard of a vibrate function.

It must be wonderful to be so omniscient about all aspects of
technology. Have you designed a nice honk-honk tone for your bulbous red
nose, BozoBorg?

Neither do. The limiting factor is the PC speakers and the sample
rate of the sound card.

CNN had a piece on special ring tones only

very high frequencies most adults are unaware

I ran a Sound Forge spectrum analysis. The prominent peak is -9dB at 18019
Hz, but there is some power, at extremely low levels, throughout the audible
spectrum. Total average power is close to 0 dB. The part that most adults
are likely to hear are greater than 120 dB down. By turning the volume, we
hear lower frequency components. I cannot tell if what I'm hearing is the
18019 Hz peak, or the lower frequency components, or DAC alias beats.

I can hear it clearly on the Grados, but not on speakers
in the computer room.

As Robert pointed out, its mainly composed of energy that peaks around 18
KHz. There are a bunch of spurious responses all over the audio band that
are about 110 dB down. They are generally inaudible.

If you play this sort of thing through the *right* crappy audio system, high
frequency intermodulation distortion (common in really cheap audio systems)
will move lots of energy down into the audible range.

I did the same analysis as Robert using Blackman
spectral analysis in Sound Forge, but with much
different results. There is a bell curve starting a
14,961 Hz ending at 15,054 Hz with a max peak
at 15,014 @ -21.5 dB. Nothing else is indicated
whatsoever over the entire frequency range.

I was under the impression that ring tones were
alternating frequencies but this appears to be just
a monolithic tone.

That sounds like what happens when you use a FFT with not enough points in
it. I used a 65,536 point FFT in Audition 2.0.

distortion (common in really cheap audio systems) will
move lots of energy down into the audible range.

I see and hear evidence of modulation by about 1500 Hz, but that may be an
artifact of the MP3 reconstruction algorithm that Audition uses.

Audibly, its got quite a few audible artifacts when I listen with my HD580s.
Oh, and I can hear the fundamental.

There may be other ring tones that fit the subject-line description.
Google "mosquito tone" to find another candidate.
