the mosquito test - how old are your ears?
i found a link yesterday about how kids are using 17 Hz tones on their phones in school to alert them of text messages. this is because the older you get, the less likely you are to be able to hear tones of the frequency. the page has frequencies from 11-18 Hz programmed into it. i was using it at work the other day and it was hilarious. i started at 18 and worked my way down until i surreptitiously observed that everyone had noticed, and it was strikingly accurate. i could hear all the tones, and as i moved down, more and more people noticed. let us know how it works for you.
give it a try

That's great, in theory... but I can hear every tone, though the higher ones become faint. I am a bit skeptical, however, that high-school students (remember, that's plural) figured this one out. Obviously enough students were doing this, that the secret got out and now there's articles written about it. I don't know. Just sounds too good to be true.
I'm old...could only hear from 14khz down. Wah!!
