Floor to ceiling question?

[Paulonbass]

Hey everyone,

I'm building a little home studio in my basement and I'm at the stage where I have to decide on what I'm going to use to isolate my studio from upstairs.

Current cross sections is:

3/4" hardwood floor
sub floor (plywood)
9" stud

I was thinking of going the rockwool between studs, resilient channel and 5/8 drywall approach.

Is this going to be enough? what kind of STC should I expect?

Should I be looking at the quietrock stuff or similar instead?

It's a one room setup.
I've built a loaded iso cab for the high volume guitar stuff so it's mostly vocals. Although I would like the option of running an amp at medium volume in there without bugging anybody.


Cheers,

Paul

2x4 stud plus a layer of insulation and **two** layers of 5/8" sheet rock would get you an STC of 35-40 if memory serves. Whether that's enough depends on what your goal is...total isolation? Not even close. Significant reduction in transmission? Sure. Remember though that the STC rating says nothing about what happens below 125Hz...that could still be a problem.

+1. NRC IR 811 shows an STC of 33 for a similar floor. Th with modest improvement is to STC 55. The Transmission Loss (TL) at 50 Hz increases from ~18 dB to ~21 dB.
