Revisiting my older research

In a recent email to fellow ITC researcher Steve Hultey, I addressed an idea I had back in 2004 (though I told him 2006 mistakenly) of using ultrasonics for the purpose of producing audible speech. You may say to yourself, "ultrasonics are outside the range of human hearing, what is he talking about?" You are correct, ultrasonics are outside the hearing range of humans, which is typically 20Hz to 20kHz but a principle can be applied to produce audible sound using ultrasonic frequencies as a carrier signal. This is illustrated in a modified version of the heterodyne principle as applied by Dr. Joseph Pompeii around the start of the new millenia.

Dr. Pompeii, who use to work for Bose before stiking out on his own was able to apply the Berktay equation (used for underwater sonar in the 1960's) in reverse to create modulated directional sound in three dimensional space. He can literally make a bubble of sound in the air that you can only hear if you are standing in the bubble. Not only that but he could make the sound directional, a literal beam of sound.

You may ask, what does this have to do with the paranormal. It has been reported in the that speech from an unknown source (presumably a ghost) has been heard by a person without others being able to hear it around them. Seems to fit a little huh? Lets go further! In many cases sound is used as a carrier to produce electronic voice phenomenon (EVP) such as running water, whitenoise generators, electric fans, etc. These items produce a carrier signal that provides raw audio to be used by whatever spectral entity, which is supported by many researchers in the field. These researchers (including myself) wondered why they could not hear the voices even though the voices record on their recorders. I hypothesize that the signal is embedded in unmodulated ultrasonic frequencies, which is why we cannot hear them. Under the right conditions, the signals can be modulated in air allowing us to hear the voices we hear on investigations.

All electronics and moving machinery produce ultrasonic frequencies. There is a whole industry who produce ultrasound meters to detect and measure these signals for inductrial applications. Presumably, the spectral entities have an electrical component as evidence of the measurable electromagnetic field as demonstrated by a myriad of investigation groups. If these entities have an electrical component in our dimensional plane then it is not unreasonable that they can produce untrasonic frequencies. If these signals are mixed (heterodyne principle) they will produce two secondary frequencies called the intermediate (difference) and the beat frequencies. If the signal is in phase with the base frequency (produced by the machinrey or electronic circuit) it will produce an audible signal. If the signal in question is out of phase, it will produce a beat frequency that is audible but only works out as a steady tick or beat. This still does not explain why we cannot hear it, right?

It is my contention that these signals lack very much intensity (volume) and are modulated only a few centimeters from the recording device. Going with this idea, how can we intensify these signals? Do we increase the intensity of the carrier signal (base frequency)? Do we apply principles of resonance to amplify the intermediate signal?
