Sound carpet

cant put a nice area rug over it ?

I'm in the process of convincing She Who Must Be Obeyed to do that with a small mobile shag carpet that was found to resolve the sound issue and will be stored away when I'm not listening to music ...
In parallel, I'm also looking for a permanent solution under the thin carpet ...

not sure how you plan on putting something under the carpet as you would have to pull up the carpet and pad from the tack strip and then have to re-kick the carpet so its tight again.

Grow a pair and tell her this is a must.

Area rug. Possibly treat reflection points at side walls, too.
