Termarock or Sonorock for the ceiling sound isolation?

Smile Termarock or Sonorock for the ceiling sound isolation?

Hello,

We got 20cm of ceiling high to scarify. And the question is, what type of Rockwool would do the better job?

Termarock 50 (16 kPa ∙ s/m²)
or
Sonorock 35 (8 kPa ∙ s/m²)

Thank you

Better job for what purpose?

Analyze what frequency range you need the most absorption for that specific application, then go with the product that has the best coefficient of absorption in that range, for the thickness you can install in that location. If thye both have the same numbers for that frequency, then go with the least expensive one.

The cheaper the better.

And... Most important is you can't isolate your ceiling only.

Well, this studio based in the basement and we don't care about side walls, most important is that we don't hear neighbours from the top.

Are you trying to isolate noise? That cannot be done with sound absorption.

yes exactly, it's about isolating unwanted noise!

I know that Rockwool it's self will not isolate the noise completely, there would be a double layer of drywall glued with green glue, Resilient channel and a layer of the Rockwool.

The question still is: what density should we go for for complete noise isolation at the ceiling?

You can use lightweight wool.

You have to consider the basic construction to calculate the improvement and if it is worth it. And be aware of flanking sound paths.

Physics don't care of what you want.

See my post above.

Depends on how much isolation you want/need.

If not we'll designed, insulation can be WORST after for certain frequencies (basses).

Agreed
Here is what I come up with.
Added double layer of the drywall with a green glue in-between and Resilient channel for the ceiling, to avoid elefant steps from the top :P

Not sure if the walls have to be treated same way as a ceiling with Rockwool insulation, as we are in the basement and nobody is disturbing us.

Cheers
