Infrasound is sound that is lower in frequency than 20 Hz (Hertz) or cycles per second, the "normal" limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing infrasound, but at higher levels it is possible to feel infrasound vibrations in various parts of the body. The study of such sound waves is sometimes referred to as infrasonics, covering sounds beneath 20 Hz down to 0.001 Hz.
This frequency range is utilized for monitoring earthquakes, charting rock and petroleum formations below the earth, and also in ballistocardiography and seismocardiography to study the mechanics of the heart.
Infra-sound is characterized by an ability to cover long distances and get around obstacles with little dissipation.

I have given a name to an extra-terrestrial race, I have called them Nubians, they said they want that name. These beings have ships in space, the same ships youve been seeing near the sun. I am in some control of them because at first they considered me their enemy. But after some conciousness shifts and working through their abuses, I talk to them as if they were equals. These are the same beings who we call voices (schizophrenia) they don't know what to do or say to people and thats why some voices are bad and some are good. they are psychic, artificially telepathic and have amazing technology that keeps them alive. Perhaps they even ressurect? Their psychotronic technology talks to planets and spirits and spiritual entities, even God and Jesus. I realise Nubian is Star Wars but they want that name. The strange trumpet sounds, hums and anything heard in your head comes from these beings, they have been trying to communicate with us for a long time but until me, they have not been able to let us "Know" who they are. Please welcome them to earth in friendship and be careful what you think about, or they may start attacking you.
