Ringtones adults can't hear? Where can I find them?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

Many of these frequencies are inaudible to people over the age of 30, enabling you to receive calls and text messages without for example your teachers or parents knowing it.
Many restaurants and businesses will play these these to annoy teens and discourage loitering and things of that nature.

However, I would like to warn you that this particular kind of ringtone is not exactly 100% health risk free. Researches have turned out that while adults might not be able to hear it, effects of the ultrasound can still influence them. Of course, those who can hear the sound will be influenced as well.
The effects I'm talking about includes headache, nausea, and dizziness. Basically anything that'll be affected by the equilibrium senses. It is true that it needs to be a prolonged exposure to have severe effects, so I guess if you answer your phone quickly enough...
