cool, i like this actually. that's a nice ring, since the high frequencies would scatter and won't go so far. in fact... i think you might as well tune it even higher as long as you can hear it.
I play stuff like this out my window really really loud on a piezo array to mess with these damn kids outside my window :B

Believe it or not, there is an actual product based on this, used for nearly the exact purpose you speak of.
It is called 'The Mosquito', and it is here:

With it on my phone, I can hear it as far as across the street, with no traffic nearby.

I can hear it. It's not particularly useful to me solely because it's not very loud. I'd have more use sticking to my current ringtone. Although, it would be useful during class since the professor may not be able to hear it and if it did go off, I could just say that it was his imagination.
I think a big reason a lot more people can hear this in person from my phone than I thought, is because I used such a wide range for modulation. I just checked the spectral on It right now, and It didn't look anything like I thought It would. See my next submission for the new hfrt (hfrt3.mp3)
-hear- it is :D
