Real world soundproofing experiences
As my framing nears it’s end I’m still undecided on what level of soundproofing to adopt in my compact 980sq ft home. The layout is attached and the focus is to isolate the bedrooms from the living space so that normal daily life doesn’t effect the quietness/sleep we love. There’s a few discussions here but I didn’t really get a sense of real life experience with different assemblies, and else where on the internet I could only find discussion focused on home theatres or soundproofing between floors. Discussions of STC ratings and frequency absorption characteristics don’t really help me figure out what level to settle on.
What I have decided is that I will weather strip and use door sweeps on solid core bedroom doors and air seal the green and yellow highlighted walls. The yellow wall will receive double 5/8 drywall on the entry wall side with sound dampening compound in between and cavity insulation.
The walls in green, I’m not sure if I go with double 5/8 and sound dampening compound, or if it’s worth going with full sound isolation clips plus single or double 5/8. The latter was the suggestion when I contacted a soundproofing material supplier. One duct will penetrate the wall from the ensuite to the kitchen/living area and at the moment I don’t plan on doing anything with the floor so I’m wondering if sound clips is overkill and will be short circuited by either of these.
I’m leaning towards the level 2 solution shown here
Any practical insight is appreciated.
