Good question...
Also, Shannon, does background noise have any impact on the ultrasonic track's effectiveness ? I.e. You were to listen to it below 25% in a noisy environment through ear buds (80-70 -db).
The picture that I'm getting of the ultrasonic track is that I can unconsciously hear it at the same volume I can consciously hear the masked track in a silent room - regardless of the background noise. I could be wrong though....
