I take it back, I can hear it. Not well, but I can still hear it. I needed better speakers is all. My friend had some good externals that worked. It appears that some standard computer speakers cannot reproduce this frequency at sufficient amplitude.

It's funny. I put my ear right up next to the speaker on almost full volume expecting not to hear a thing. When the sound clicked in, it made me jerk my head away. I don't know if this makes sense. The sound was hard to hear, but it "felt" loud. My ear still feels weird.
