Damn guys, the high-pitched teenager-repellents won't work on me anymore!
(I can kind of hear about two up from there, but not well enough to convince myself it's not all in my head.)
The *real* interesting game to play with this set of sounds, of course, is playing more than one similarly-pitched tone at a time and listening to the tone that their interference creates. (There are a bunch in easy hearing range here. If you are super-badass, you can tune your guitar using this phenomenon...)

You are about 20 years old |
The teen repellent will no longer foil you, but you can still hear some pretty high tones. The highest pitched ultrasonic mosquito ringtone that I can hear is 16.7kHz |
Find out which ultrasonic ringtones you can hear! |
