A few years ago I was studying the components of EVP and our atmospheres response to soundwaves, I stumbled upon a rather reliable technique. By using a frequency generator and a ultrasonic transducer I could project ultrasonic waves into a room and would record very good EVP's and even get audible speechout of thin air. It seems that nature has it's own brand of simple heterodyning. I only tried this in houses I deemed to be haunted by other recorded and measured activity. Anyway, the broad sound spectrum I noted seemed to work as a reference. I thought I would post it here to see if you could put it to some use. Let me know if you have any questions.  Harmonics:

Hi fratka Is this the same procedure as charging a room before recording?

No, you allow the ultrasonic transducers to operate while recording. You will not be able to hear them so don't worry about audible interference. Don't set the intensity too high on the transducers though, they can make the microphone membranes distort, which will cause recorded interference. Frank

Hi, The chart shows 3 coloured areas. I presume the red frequencies related to class A voices received, using each of those 12 frequencies shaded? With the frequencies themselves, did you radiate single frequencies of the 12 that are shaded red, between 20 and 40kHz or were multiple frequencies radiated? JEFF

Multiple Freqs were radiated at once. This was early in my EVP research so even though it worked it didn't work for the reasons I thought it did. It was the complex sound generation by the intermediate harmonics of those beat frequencies that was allowing them to use and manipulate the sound. At least that is the present running theory. I tell you what it was the goose and rabbit chases that taught me the most about this stuff. Even though a lot of them didn't pan out I learned something new everyday. LOL Regards, Frank R.

Thanks for the clarification. One other related question: did you use a special mic for recording (response into ultrasonic region) or just ordinary mic? thanks, JEFF

I used a normal mic, I wasn't recording the ultrasonic sound. I was recording the intermediate frequencies they created through heterodyning (mixing). The lower intermediate frequency was usually well within the hearing range of humans though the upper and primary freqs were not. Frank R.
