Most soundproof kind of carpet padding?
« on: September 06, 2006, 02:28:40 PM »

I just bought a two unit building with friends and live in the lower unit.  There is quite a bit of transmission of voices between the apartments.  Also, footsteps are clearly transmitted.  

These units have beautifully refinished hardwood floors, which we don't really want to mess up.  We are also not in a financial position to modify the lower unit's ceiling right now. Our ownership agreement does specify that most of each floor will be covered. We have large persian-type area rugs for this purpose. We have decided that our first step will be to put down the most noiseproof kind of carpet pads we can find and see how much this helps our noise problem.

Any advice on the very best kind of carpet pad for sound proofing?

Like most things in life, the best stuff is usually the most expensive.  

It probably won't help much with the airborne noise, but it will definitely quiet the footfall and structureborne noise.  Aside from a floating floor, carpet and pad are about the best things you can do to deal with that.

Think about using some of the MLV+foam product sold on this site.  You can use it in place of a carpet pad and, provided you seal up and tape the seams and edges, it will block some of the airborne noise too.

You have a real dilema. Do you want to continue to be able to view your hard wood floors or do you really want to soundproof your floors?

Using Closed Cell Foam that is laminated to Mass Loaded Vinyl as a carpet underlayment along with rebond rubber carpet pad and carpeting of your choise can provide superior air borne and impact sound control.

If you do not fully cover the hard wood floor area from edge to edge, you run the risk of the unwanted sound transfering below.
