When masking the varying amplitude 440Hz tone with a 400 Hz tone, the masking effect was
not equal for equal amplitudes before and after the peak had passed. Why was that?

Sometimes when I'm in my room I hear a high pitched buzzing/ringing sound. The sound isn't just in my head because when I turn my head and move around the room, the sound still seems to be coming from the same place, my TV. The sound seems to be there sometimes even when the TV is off too. My TV is fairly old. What could be causing this noise? I wasn't sure where to put this question, but since it may have something to do with something in my TV, I put it here.

At first guess, from looking at photos of counter-rotation blades, I would imagine that there is a gear system which changes the rotation of one set of blades (on a common shaft) in the opposite direction to the other set of blades.

Does anyone have a clear way of explaining this to me? Or better yet, does anyone have a diagram of the internal workings of the counter-rotation process?

I'm a manufacturing engineer and seem to be the go-to person for technical questions in my office. I don't know the first thing about commercial construction or building codes. I am assuming that accessibility rules are contained in the provincial building codes and enforced by those bodies responsible for them.

But I have a colleague who insists Canadians must abide by the ADA (which sounds like nonsense since American laws don't apply here) and that our new offices do not conform.

Can anyone offer some insight?
