What evidence is there that we hear Ultra Sonic audio?

[Shannon]

I had my ultra subs on while sleeping, and my son came barging through my door and went straight to turn it off my player because it was too loud and annoying for his sensitive ears.
Young people can hear it easy.
I have heard stories that after banning cell phones in class, kids started using ultra high freq. ring tones because so other kids could hear them, but teach couldn't-amazing.
I wish my ears were that good!

does your son hear it as clear as normal audio, the actual words of the hypnotist or is it more of a pitched sound with a certain quality?

Two points here in response. First, hypnosis and subliminals are usually done separately, because they work in different ways. So the vocals on a subliminal aren't necessarily coming from a "hypnotist".

Second, as far as my research has taken me, even those with unusually sensitive high frequency hearing cannot make out the words if they are shifted into the umbra ultrasonic. However, that said, my programs are created using a series of specialized methods that make it difficult to understand the words consciously even if you could hear them without being made subliminal. The subconscious still understands it perfectly, and the technique makes for a much improved amount of information flowing into the listener's mind too.
