To clarify, the ultrasonic subliminal track actually is audible. However, it is primarily audible to the subconscious mind. We believe this is true because of the physics of the ear; the eardrum is simply not small enough to efficiently vibrate in resonance with pitches that high. However, smaller structures within the ear can and do resonate with these pitches, but are not connected to the auditory processing centers of the brain. In effect, you can get results from ultrasonic subliminals because you can "hear" with the part of your brain that senses balance through the tiny hairs in your cochlea, which is the snail shaped part of your inner ear that regulates your sense of balance.

You'll know the program is working because you get results.
