So, I have a question. Let's say you're going to take out carpet from a room and want to put down some hardwood floors. When you have the carpet taken out can and the hardwood flooring installed, is there some kind of material you can put down before the hardwood to reduce noise and maybe even vibration? Would I have to take out the bare-wood panels below the carpet and get in between the floor below me ceiling and the floor and add something there between the two?

Just wondering if any of you have any experience with this. :)

Thanks!

Yes, there is something you can put there. It heavily depends on what kind of soundproofing you want. Do you to soundproof speaking noise or do you want to soundproof walking noise?

What about price? That stuff on acousticflooring looks as if it will cost a very very pretty penny...

The best solution to reduce noise and vibration would be :

wwwwwwwwwwww Shiny new wood floor or carpet or tile
-------------------Underlayment like quietwood
XXXXXXXXXXXXXX Foam
[[[[[[[[[[[[[[[[[[[[[ EXISTING FLOOR

And its done.

no need to remove anything

This. Are you talking about supressing the "thud" sounds of foot steps to the floors below or are you talking about reducing echos within the room?

You need to make a "box within a box" .....

So, build a new room, inside of your room at your parents house .. I'm sure they will just love that .... Then, suspend the new room above the old room using magnets to keep it from touching .... It'l be floating on air, so when you step, it keeps the noise inside, and makes it so nobody in the rest of the house can hear you.

Or instead of magnets you can go with RSIC clips.

A: Concrete/tile board with a thin layer of foam over it. The foam comes on a roll and is normally used under hardwood anyway. The only weird thing would be the concrete board. The concrete board is dense to reduce noise penetration. The foam will damp vibrations. This will cost roughly $1 per sqft, and make your floors a half inch thicker, assuming you are already having the floor replaced. A half inch thicker floor will probably add some labor cost with non-flooring items, like removing and replacing all the baseboard and shoe molding (if any), cutting doors, cutting door frames/jambs etc. Depending on the room, this could get quite costly.

B: Use denser hardwood. This could easily get very pricey. Brazilian Cherry (really a rosewood) is much denser than Red Oak or Maple (most common hardwood flooring in NA) and far more expensive. Most high density wood is imported, rare, and super expensive.

C: Use tile instead of hardwood. Over one inch of stone and concrete on the floor will keep out a lot of noise. Far better for this purpose than any wood.

D: Why does a teenager, living at home, with no job, and very little sense, need to know this?

Strand bamboo is a reasonably priced uber dense product. That stuff is like battleship armor. You can pick it up for around $3.00 to $3.50 a sq/ft. It's only .55" thick though and not the more common .75" of "real" hardwood.
