The EVP (Electronic Voice Phenomenon) demystified

Above this text is the trailer of the fictional movie "White noise". The movie is basing a true phenomenon, which can be paranormal. Or it can be made by using subliminal sound systems, which purpose might affect the behavior of the targeted people. Or it can be caused by sonic or acoustic crystals, which can theoretically store voices like speech.

The EVP (Electronic Voice Phenomenon) is a computer-based system whose purpose is to strengthen and clear the extremely weak sound, and the system is created for detecting submarines, but this system is also used to make surveillance tapes more clear in the police and intelligence eavesdrop tapes. The system is also used to detect things like subliminal acoustic affecting systems. The subliminal acoustic systems can send simultaneous commands, what purpose is to make a person do something, what the targeted person would not otherwise do.

So what is the EVP detects the voice of a dead person? Sometimes there is the possibility that somebody will play the records, what are made about that person. So is the purpose of that thing to make the targeted person a maniac? There is evidence that the infrasound-based commanding tools are tested by governments, but those systems can also operate by criminals.

Can acoustic or sonic crystals answer those mystic records of the voice of the dead?

But the EVP has caused one very interesting question. Is it the possibility that some stones are storing the sound? There are optical crystals, that are storing light, so is it possible that somewhere is acoustic crystals, the material that stores pressure waves, and then releases them in the order when they are stored?

These kinds of things like nanomaterial, what can store sound are interesting things, what might be very useful, if they would have existed. If we want to store the data or speech to nanomaterials, those materials must store and release the pressure waves in the form where they are stored.

If acoustic crystals exist those things can be used to store data in the acoustic form. In that process, the data would transform to voice and then that voice will be stored in the acoustic crystal. When that data is needed, it would play to microphone, what transfer it to electric signals, what are send to microprocessors. But that system requires the existence of acoustic crystals.
