As I noted before...I'm a piano tech. Been doing it 40-50 hours a week for 25 years. Having said that...it's hard to say what's causing your noise without seeing it but here's some possibilities.
1. Sometimes the spring under the trapwork (that's the wooden bars that are hooked to the pedals) will be a leaf type spring and it will rub against the bottom of the trapwork. it's usually padded by felt and that will rub through. Either glue a new piece of felt or squirt some graphite up in there.
2. The dowell rod that goes up from the trapwork has a metal pin that fits up into an opening in a little metal bar and that's where it lifts the dampers. There is usually a rubber piece that cushions it and that will sometimes squeek. Same thing...graphite. But sometimes the rubber piece tears up and falls out. You'll have to cushion that metal pin at the top of the dowell rod some kind of way. I always have replacement parts but you, of course, don't. A piece of felt will do it.
3. Loose screws in the trapwork...the screws holding the spring down usually. Tighten any screw in sight.
4. Somtimes the side of the pedal itself will rub on the hole where it passes through the cabinet. If so...recenter it.
5. Old damper felts can get hard and make a noise when settling back down on the strings because the vibrating string slaps against the damper for a second. Only thing to do is replace the dampers which is something you can't do yourself. get a tech.
6. ....there are some noises that damper mecahanisms make....period. Lots of times people never notice 'till they're in a situation that calls it to their attention. I'm not saying that's the case but it is possible. That's why mics inside the piano are a bad idea. there are all sorts of mechanical noises going on.
7. Everything that hits or pushes on anything else has to be padded with something. usually felt. Felts fall off and you'll need to make sure they are in place.
There are others but these are the most common. Good luck.
