You know I suppose a very easy way to just test this out is to get a dog whistle and a few random recorders (sorry, I haven't used an actual tape recorder in years!) and see what the results are when played back...

I think I recall that test at Eastern State - that was where they had some big speaker hidden and had people come into the room that didn't know it was there, right? Good experiment...

Oh - do you use some sort of vibration sensor with your experiment? The elephants and the test just brought that to mind...

Just a question... doesn't the human ear having a certain threshold of hearing and the recorder's ability to pick up sounds lower than that threshold - then play those same sounds at a level that can be heard kind of go against your theory?

I'm no tech geek, that's for sure - so please correct me if I am wrong about audio recorders being able to do this...

In my research not necessarily. However, you could get a recorder that does but a simple normal one speed TAPE recorder works pretty much the same as an ear. Obviously if you got a more sophisticated model with multiple speeds you probably could detect and be able to play back more sounds but not necessarily a spirit voice. (IMO EVP and spirit voices are different.)

There is also information out there that shows that there are sounds below the human ear's capability of picking up and that a recorder can pick it up but only heard if played back differently. Such was the case in the discovery of the low rumbling sound that Elephants make. That was discovered by mistake when a recording of Elephants was played back at a different speed.

So too it has been learned that low frequency sounds cannot be detected by the human ear but can be physically felt by the body. Referencing the experiment done at Eastern State.

A whole lot more to do and learn on this subject beyond just turning on a recorder hoping to catch something.

So..yeah, theory should be sound /smile.png' class='bbc_emoticon' alt='' />

I have adopted a theory of my own regarding EVP's. I still believe EVP's may be spirits but, that spirit voices are not physical sound but electronic impulses picked up by the recorder or tape directly, not by the microphone. Then transformed into sound.

Now hear me out. Simply put, microphones pick up changes in air pressure. The sound waves are picked up by a microphone which converts them into electronic impulses. These impulses are amplified in the recorder. Then pass through the heads which give out a magnetic impulse and then recorded on the passing tape. Now, roughly speaking on a normal recorder, a microphone is designed to pick up physical changes in air pressure and the sound waves are in a range closely comparable to the human ear.

This being the case, any spirit voice picked up by a microphone should be heard by everyone present when it was recorded. However, they almost never are????? My thought is that if they are heard then they are physical sound and probably not a spirit. Remember EVP is electronic voice phenomena not spirit voices. We can debate that later. LOL

I believe, that spirit voices may be the impulses made by the energy produced by an entity and not physical sounds emanating from the entity. So, maybe, in certain conditions it could be directly picked up by a recorder. Maybe the spirit voices we are catching are bypassing the microphone and maybe microphones are even interfering with capturing the voices or masking them because they pick up outside physical sounds and we are missing more than capturing.

Now, I am also experimenting using a tape recorder with a disconnected microphone in conjunction with a normal recorder. Some interesting results but nothing conclusive so far. However, I am confident I may be on the right track for the time being.

Now, as with any research we always come across some new ideas. I also have another theory based on the recording of sound that may show that physical sound from someone who has passed on may be a possibility. However, it is their voice, literally from the past and not their spirit voice. So it doesn't conflict with my other theory above. I'll save this for another forum or blog.

Lastly I will close with one of my favorite Einstein Quotes; If we knew what it was we were doing, it would not be called research, would it?

GB - Are you still using tape? I think most everyone else has gone digital, but analog tape does have some advantages, once you get past the atrocious S/N ratio. Makes me wonder if I should get a cheap videocassette recorder to run in parallel with the digital units (on which my wife has cornered the market - we have about half a dozen). Have you gotten better results with tape?

GhostBreaker would it be ok to remove the film that is connected to a microphones coil to test this?

This could be very interesting. I'm sure there will still be residual sound from bumps and jostles......

but still very worth trying.
