How do you know this? Have you succeeded in performing this mental exorcism, and are reporting your findings?
Wait. When did they become ghosts?
Well, I mean unexplained entities. See I have my own personal theory that voices are indeed spirits of the dead, and will fill in the emotional position you hold for a person that you have recently had contact with via face to face or through any form of communication that is real. The feed off of life and when they change person they become whoever corresponds with the next person's thoughts. The voices are godly in human nature and love a good joke and they love to play it on you or if they are just totally unaware that they are expressing super human power responding to every little word of your thought is a good question. If you do not ask or respond with your thoughts to the ghosts they feel ignored and pretty much go away, however with schizoids the voices are very prominent and all the silence in your head that you can meditate won't get the malice to seize.

Well, basically yes, and remember I said they react not stop. Apart of schizo is feeling demeaned by the uncontrollable nature of the voices belittling the sufferer. Giving them a tool to resist with is good. It's very simple to do, just use a ear headphone and plug it into a microphone socket and record in as silent a condition as you have. However, like i said in the OP, I m looking to increase the sensitivity of the mic since you're looking for tiny vibrations from the vestibular/cochlea, by using elastic in the mic.
I've been basically practicing being a mystic for about four years which basically means incubus. I went into it aware that it was dangerous and that mysticism had been denounced by Hippocrates as unreal some two thousand years ago. It definitely has a real powerful effect on the person who practices it. I've heard voices from others and in the sound waves coming out of different objects since I was 16. No one ever called it schizoid because it wasn't schizoid till I started responding or being a mystic. There are certain things about being powerfully mystic that are involuntary and observable, example: the dizziness in the vestibular balance system.
It also helps to stop the voices by telling yourself they are responding to your thoughts, then remember that no matter what insane, messed up, vulgar thing you think in front of a person, it has never been uttered in history "Hey, why did you have that thought?" That's why I say ghost and not human however, all of this is just theory of the unexplained so, Idunnno
