Hearing Test Sounds at 6 - 15 - 20 hz

Listen for the first time without headphones and then listen again with headphones. It is recommended that you turn the audio to maximum. Notice as you listen with the speakers, that you cannot hear any sounds. Instead by having headphones you are able to listen to some vibrations, also you can hear how these frequencies produce different sounds. Human hears cannot perceive frequencies that are below 20 hz. Yet we can hear something by using headphones. All of this will have a relation with the GhostArk, once the time is right. www.ghostark.com
