I am going to be thirty freakin' five later this year, and I heard it. And I'm a factory worker. You know, lots of ambient noise and stuff slowly eroding your hearing, but I have excellent hearing. I chart all the way across the top of their chart last time they tested me. So I have excellent hearing, I just don't listen.

And that is annoying. I remember going to the computer rooms in high school (all Apple II's) and one of the monitors always bugged me because I could hear when it was on because it made a noise like that.
