I listened to the ultrasonics last night. It was a little odd in the morning, because I wasn't sure if they had been effective or not. With the waves, I awoke in the morning feeling sure that I had been listening to subliminal messages all night long. I know I have the ipod dock at a good volume, any higher and I feel temple pressure, and higher still I can hear a distinct high pitch noise like gears squealing. I think it's similar to turning a song with lots of bass up on low quality speakers and the bass distorts on the lowend. In this case it's distorting on the high end.
