Shannon I was just curious where did you come up with the idea to utilize ultrasonic subliminals? At first I didn't understand how they could possibly work, but I've been doing a little research and what I have found has fascinated me.
"The upper frequency limit in humans (approximately 20 kHz) is due to limitations of the middle ear, which acts as a low-pass filter. Ultrasonic hearing can occur if ultrasound is fed directly into the skull bone and reaches the cochlea through bone conduction without passing through the middle ear."
Now it says "fed directly into the skull bone" which would require a device of some sort that is in contact with the skull. But it seems like these ultrasonic subliminals are still able to vibrate the inner ear through the air. Is the principle still the same, bone is being vibrated within the ear to hear the messages? This really is amazing how we can decipher these messages even at ultrasonic frequency.
