About this app
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!
