I've noticed another odd thing. I'm blessed/cursed with absolute pitch, and once in a while I have enough trouble with wax buildup that I have to break out the ear drops and squeeze bulb. When I flush out the ear with trouble, that ear's pitch sense goes awry; dial tone sounds a half-step flat, for instance. Once that ear dries out, it's back to normal.
