Carpeting with extra thick padding is a traditional recording studio standard. The idea being “the squishier the better”. What this does is it absorbs the sound waves before they hit your sub floor surface, whether it be concrete slab or a raised foundation. With today’s newer materials, we are moving more towards eco-friendly, recycled products that are made specifically for floor sound proofing treatments.
rwt design and construction
There are different products on the market today that are very costly, that just regular silicone can take the place of. When sealing joints, boxes, wall to floor etc. just regular silicone preforms exceptionally well. This can be purchased at your local hardware store for less than 5 dollars a tube. I would suggest purchasing this one case at a time when constructing a new studio.
