Assuming this is a new area rug and not wall to wall, I would find a piece of foam carpet pad at the big box stores. Have it cut to size just smaller than the new rug by a few inches, and place it underneath. The extra padding could help. And it won’t cost you much to give it a try.
Sound carpet
Hi,
Recently my wife replaced my beloved shag carpet in the living room with a thin one and sound became cold and noisy. When I return the old one sound is warm and quiet again.
Any solution you know of ? Any product exists that can be put under the carpet that is not too thick for She Who Must Be Obeyed to complain about ?
