Well, imho biggest source of noise (reasoning by track pads noise going down on track) for track pads is that their working temp range is too high to be reached during normal braking driving on public roads .. so bedded layer quickly wears down, resulting in squeal. Track crowd usually takes extra care to keep brakes working properly, frequently switch pads, so wear level rarely comes as surprise and thus i don't think that pad high wear is common noise culprit.
For street pads squeal might be due them worn too much, and as many of them have "brake wear indicator" in form of embedded metal plate that scratches disk with noise once high wear level reached. People only daily driving their cars often care way less about regular diagnostics and also often try to use parts (including pads) past reasonable wear rates ..
As to OP, if wear level is certain to not be issue (has he checked pad thickness?), i'd think first of trying to rebed brakes with repeated hard stopping and see if that doesn't fix noise issue. "should still have some life left" sounds more like guesswork, not measurement.
