Listen to various high frequency sounds!
The pitch of a sound is determined by the soundwave frequency. These high frequency sounds are made by fast sound wave vibrations, while slow vibrations create low pitched sounds.
As you age, your hearing abilities decline so that you are less able to hear high pitched sounds. This means that these high pitched sounds are effortlessly heard by young people, but not so easily detected by older generations. Test your hearing (or your parents’ hearing!) with these high frequency noises!

Ratings and Reviews
Some people are saying it doesnt work in their reviews. They just arent young enough to hear it. It really works awesomely.
HIGH FREQUENCY APP
It is a great app to prank ur friends at school and just cool like I was walking down the hallway with it on its just funny how the people react at my school to it
Can’t stop tone
There doesn’t appear to be a way to stop the tones. You can change frequency but it keeps gong until you quit the app.
