Yes. The title says it all. It is a ringtone that uses frequency as high as 17khz. Adult cant hear it. Try it now. .mp3 -> http://www.monsterupload.us/867460 (118 KB) .wav -> http://www.monsterupload.us/702837 (1.68 MB)
what age is the supposed cutoff?? I'm 34 with 'damaged' ears (constant ringing)...just b/c the mp3 player goes to '25' on the volume doesn't mean I should listen to it at 25 I know this now. I can definitely hear the tone. "Yeeha, Jester's dead!"
