Loose or worn rubber washer? Check the seat while you
have the stem out.

I have been trying to diagnose a plumbing noise problem
with no success and would appreciate some more seasoned
advice.

When I open the upstairs bathroom sink cold water faucet
just a little I get a strong loud vibrating sound. It goes away
as I increase the water flow.

No problem with the hot water faucet or downstairs faucets
(hot and cold). I first thought it a hammer problem but that
supposedly only happens on closing faucets and anyway I
did bleed the system to all air back into the air chambers.
But this ghoulish noise persists.

Pointers much appreciated. Thanks.

I had noises like that and found that nearly all my pipe supports had pulled
out.
But I expect there are many causes for plumbing noises.

Could be a loose disk. The cold water faucet could have a disk
floating around and vibrating as it throttles more, and vibrates less
as it throttles less.

This would lead me towards repair/replace the disk.

Just a guess... Not your plumber.

Google for "seat chatter."
