The worlds famous sound that adults cant hear is now available on iPhone !
This is the Original Crazy Sound which can only be heard by people under 24 years old !!

HOW DOES THE CRAZY SOUND WORKS ?

The Crazy Sound is a mix of several Ultrasonic Sounds too high pitched for most adults to hear : after 24 years old, you (normaly - try it !!) loose the ability to hear high frequencies.
This is why 95 % of people older than 24 will not hear the Crazy Sound !!

And you, can you hear it ?
And if you hear it ... can you bear it ?????????

Have a lot of fun playing with the Crazy Sound (teachers wont hear it !!! ) , now available for iPhone on the App Store !!!!

NEW ! This version also include the Xtreme Sound, specially mixed to be unhearable for people older than 20 years old !!!
