Even though you can't hear these frequencies, they add
something subliminal to the way the music affects you.

Interesting theory, but how are you going show that this
is right if there are no conscous affects?

Oohashi measured brain waves to do this.

And if you believe that....

Why don't you dispute it then?

It obviously does matter. While one ear is deaf to the effect of sound above
20kHz or so, two ears are differentially sensitive to 50 kHz or more From
http://web.mit.edu/2.972/www/reports/ear/ear.html, the ear is sensitive to
the difference of arrival time of a sound to each ear to 10 microseconds.
Quoting, "The brain is sensitive to differences in time of arrival of as
small as 10 microseconds, and can use this to pinpoint the location of the
sound." This corresponds to a steady state tone of 100,000 Hz.

No one can hear a 100kHz tone. However, when an impulsive sound occurs, the
difference in spatiality is noted as if the ears can jointly (not singly)
resolve a tone of that frequency. Simply put, ultrasonic components
influence how we localize sound. As spatiality is one of the most prized
aspects of the stereophonic experience, it is obvious that ultrasonics do
matter.
