My piano drives the person below nuts...
I've got a digital piano with headphone jacks. Usually, I use headphones when I play (especially when I'm practicing a new piece). So, no sound gets out EXCEPT the thumping of the keys. The keys have that realistic hammer action mechanism that makes them feel like grand piano keys, but they produce a nice muffled thump every time I hit one. Of course, that muffled thump tends to travel down the frame of the piano, through its feet, and through the floor to vibrate the ceiling and walls below... just enough to annoy the person. It probably sounds like someone lightly pounding their fists on the floor repeatedly and quickly. (No, I don't play very hard. The sound just travels extremely well)
Now, the person below me has to get to bed early and get up early. The only time I usually get to play is in the evening, when they're going to bed. To make things worse, the only place I could fit the piano was in my room, which is directly above their room! I've tried placing bundled towels or foam rubber under the feet of the piano, but nothing seems to work.
Does anyone have a suggestion? Is there some sound absorbing material (perhaps in mat form) that I can put under it?
Anything to stop the thumping (and the resulting wham! wham! wham! wham! I get when the person below hits her ceiling to make me stop).
