Simply generate a tone with a frequency Generator between 1Hz and 22000Hz on your smartphone or tablet. Test your hearing and that of your surroundings by determining the range of frequencies that you are able to hear. On average, the human ear perceives frequencies between 20Hz and 20000Hz, but this perception can deteriorate with age, especially for frequencies close to ultrasound.
Experience the acoustic beat phenomenon: For example, launch the application on two devices and then generate a frequency of 440Hz on one and 443Hz on the other.
Test your speakers and other audio devices.
Use the cursor or the keyboard of your smartphone to adjust the frequency, then click PLAY to play the tone.
