A just has a kind of a buzzy feel to it. It's not something I can really quantify or prove, just a sort of synaesthetic sense. I would say that I feel it the strongest in the two octaves below middle C. It is basically true for any piano. I don't have a mapping for all 88 notes on a piano, and it's not like you could hand me a timbre and I could identify the corresponding pitch. The whole thing is shifty enough that I assume something else is actually going on and this is just the way that my conscious brain makes sense of it. But it is part of the way that I perceive pitch.
