The human ear can detect sounds that vary the frequency from 20Hz to 20000Hz. I mean, he is able to detect these sounds when it is brand new. With age and small abuses, such as concerts, gridlocked traffic and MP3 players, we gradually lose this ability.
It is not uncommon for people over 25 years no longer can hear sounds above the range of 15000Hz
This software aims to make a simple test to see how often you can hear.
