The other morning while messing around with some sound effects in the studio, I played a few random noises for just us to listen to .  Immediately, Jess started freaking out and quite frankly, I thought she was joking.  Turns out, I was playing some audio that I personally couldn't hear, but she could.  And it was driving her crazy.  Do you hear this annoying frequency?
