I'm returning to the subject a bit because I have the same problem.
On Saturday, my new piano finally arrived (previously I played on a digital) and having placed it in a room that is still empty, the reverberation is very annoying.
In any case, the room will be furnished shortly, so there will be a sofa, some furniture, a rug, etc....so I don't know what effect that will have later, however, I would like to understand how to limit the reverberation...
I should preface that my interventions do not have the goal of soundproofing but of improving the acoustics (which I think also translates into a more pleasant sound perceived from the outside).
The room is about 30 sqm. In your opinion, what interventions could I make? For example, is putting a sound-absorbing panel behind the piano useful? Or putting them high up in the corners? Or in other strategic points like something on the other walls as well? And if so, what dimensions should these panels be, and those placed in the corners?
I saw that, for example, at Le Roy Merlin they sell panels and the cost doesn't seem high to me....so I could easily get them...but I have no idea about their dimensions or how many and where to position them.
