Sound isolation in an apartment in a concrete building

[oscillation23]

Hello,

I am moving my project studio into a concrete building. I will have neighbors beneath me. The flooring is currently tile on top of concrete; I plan to install thick carpet -- but would like to take it a step further by putting a layer of... something beneath the carpet to help with isolation even more.

I found a product on soundaway.com called "soundproofing carpet underlay"
(sorry, it won't let my post a direct link since I'm new to the forums) --

"SoundAway Premium Barrier Carpet Underlay (11015), combines a layer of soundproofing barrier and a dense, sound-absorbing, and sound-blocking, closed cell foam. This soundroofing composite decouples two rigid surfaces serving as an isolator, sound barrier, sound absorber and a fabulous carpet underlay."

I'm wondering if anyone has any experience with this, knows what it is made up of, if it's any good.. or if it's even the right thing to do.

Could I accomplish something similar with a combination of rubber and dense closed-cell foam?

I would love any advice anyone has to give!

Thanks much
erika

What for? your floor is concrete? It takes a lot of vibrate concrete.

Just put some gramma pad's or subdudes underneat your subs.

Now I do suggest you find something to make putting your bum on the floor comfortable.

Yes, my floor is concrete; however, it's a residential building and I really don't need what I'm working on to reverberate into the lower unit... and sound has been an issue in the building, at least as far as hardwood or hard flooring goes (they frown on it). I'd way rather be safe than sorry on this one.

shows you a bit of how to build a floor that's sound proof.

However it's too much work for me.

i live in a modern concrete condo building. i have no problem moving this building.

the only way you are going to stop the sound, other than not making sound. is to build a room INSIDE of your room.
