HEARING TEST

Set your volume to regular settings, as if you were watching any YouTube movie. Watch Hearing Test and listen very carefully using headphones. The video displays audio frequencies that are being played. You can determine what you can or what you cannot hear. Typically, depending on age, audible frequencies will be between 20-30 Hertz on the low side of the audio spectrum, and 10-16 kiloHertz on the high side of the audio spectrum. There are individuals, however, who can can hear the whole spectrum between 16 Hz (Hertz) and 20 kHz (kiloHertz). Because of the encoding used during the audio preparation, tests above 18 kHz are not very reliable.
Please make sure that you do not increase the volume just to see if you can hear anything!
