DIY hanging of ROXUL safe'n'quiet
« on: August 21, 2019, 12:47:07 PM »
I'm having problem with noises from neighbors upstairs. Getting a proper room in room solution is kinda expensive (quoted upward $20k for ceiling and walls, without noise clips). So I'm thinking to DIY hanging rockwool panel or sticking them to the ceiling somehow. Does anyone have experience with this kind of DIY? What kind of reduction is possible? I'm thinking to start with a layer of 2 inches and adding another layer if that is not enough.
Thanks.

if your doing this for room absorption and reflection it will work.
BUT, if your doing this to reduce impact / footfall noise it will do very little if anything.
You would need to decouple using clip and channel or double joist system.

Randy, from your experience, how necessary is the wall treatment if my main purpose is to block impact noise from the unit above?

Is there an example recording somewhere on the reduction achieved with ceiling treatment? Just want to make sure that I have the right expectation.

Thanks

I always start with the ceiling treatment as that is the main location of impact transmission.
You will have some value of flanking noise down the walls, unfortunately that value is unpredictable.
I've seen flanking as barely noticeable after the ceiling treatment and I've had it extremely noticeable other times, usually when lathe and plaster are involved or you have a structural issue before hand which does not get addressed.
As for the recording question...not that I know of and if you could find one that doesn't mean that will be your value of reduction.
Your value of reduction will come from how many principles you apply to the assembly and how well you install the materials. Devil is in the details. Mistakes are costly and can greatly hinder results.

feel free to contact me direct.
