Did the original Neurophone use electric signals, whereas the Echofone uses high frequency sound vibrations? I wonder how the difference between the two methods felt...

Thanks.

I have used various electrical devices that ran electrical current through the body. One of these devices is the Brain Tuner by Dr. Bob Beck that many people have built. See http://www.braintuner.com/braintuner.htm for more information on one of the models. I've also used this device along with listening to an audio program at the same time (including a light sound machine). The Brain Tuner also includes a preset for the Schumann Resonance frequency for meditation.

I am able to hear sound signals fed to the Echofone transducers, so there seems to be a significant percentage of the normal sound frequencies (less than 20,000 cycles/per sec for perfect hearing) being output by these devices.

Do you think there is an even higher percentage of higher frequencies being output, which we cannot hear with our ears, which are being transferred to the nerves or brain via bone conduction? Which have you found to be the most effective place to place the transducers - the temples or on the bone just above the ears?

Thanks for sharing your knowledge and experience - it is much appreciated. You seem to have a vast set of experience with all these different devices and techniques.

The echofone micro-massages the middle ear and stimulates the inner ear just like a Tomatis recording does. The echofone can allow you to hear the overtones that lie above your hearing range. I like to use it with a Tomatis recording since it emphasizes the higher frequencies. I prefer to place the electrodes directly on bare skin which leaves the temples or forehead region, so that hair is not in the way. I haven't tried placing them under the ear or on the jaw but maybe I'll try that sometime.

High frequencies will energize you while low frequencies will drain you. (Note that Holosync likes to emphasize the lower frequencies.)

My Question with the Echofone is: When using say a Paraliminal Tape, can you actually hear words that Paul says? Or is it just a transmission of vibrations and frequencies?
Both would be nice. Also do you feel it really makes any kind of difference?

The Echofone has two outputs - one to the high frequency transducers, which are like little speakers, except that instead of a paper cone which vibrates, these transducers have a metal plate which vibrates. The second output goes to normal headphones which you place over your ears.

The high frequency transducers, you place on your temples or other places on the head, and they are supposed to transmit the high frequencies to the brain via bone and skin conduction.

I am able to hear the sound from the transducers using my ears (normal hearing), which leads me to believe that the transducers send a combination of normal audio signals (which I hear using my ears), and higher frequencies, which I "hear" through bone conduction.

The difference between using just the headphones, and using the headphones and the Echofone transducers, is that sounds appear to more 3-D in nature, and definitely more clear, because of the higher frequencies being transmitted by the transducers.

I am trying to discern how much of an effect using the Echofone has when using paraliminals or other accelerated learning techniques, because that is what the Echofone brochure says it can help with.
