does noise reduction insulation work well?
Author: admin Category: Noise Reduction
i live in an apartment and can hear my neighbors footsteps and noise from above. was recommended having celluloseblown into the ceilings.
I think not a whole lot of help.
The drywall on your ceiling is nailed to the bottom of the floor joice and their flooring is nailed to the top. So the vibration (noise) of walking gets transmitted right through. Insulation would dampen only the noise in the air space but my experience says it will reduce it a little but not address the real source.

Hello,
That will help, I always put an R-30 between my floors when I build so you can’t hear much at all . The biggest trick to noise reduction is overlaps of products and differing layers as that these things by overlapping and varying in thickness will act to deaden with each layer.
For example in a indoor movie theatre they will fill 12" block walls with sand and then each auditorium wall gets 2 to 3 layers of sheet rock. If they are smart, the layers will be 1/2 then 5/8 then 1/2 again with a dead air space or insulation between each one.
Well that’s how we do it. In an attic , blow hard - because cellulose will settle and you don’t want air space to be able to capture moisture , so pack it tight.

I agree with Thor. In my townhouse condo, it was the party wall noise that was an issue. The neighbors to the side weren’t loud but you could hear every little thing. I had cellulose insulation blown into the walls, and it did help a little, but not very much. The common structural elements continue to transmit the noise. In better construction there is more effort to keep noise transmitting connections down - going in after the fact to try and resolve the existing situation with insulation doesn’t make up for poor construction, unfortunately.
