This is the best way to soundproof a room..

Apartment builders are taking notice and promise to do the opposite of this.

Been insulating, drywalling and taping houses for 23 years and I always ask the homeowners if they want us to insulate certain rooms and they usually say no it should be fine. 6 months to a year later I'm back in these homes sound proofing those same rooms. What would have cost them $100-$200 in extra insulation ends up costing thousands in renos. Listen to the experts people.

I've been building houses my entire life and I have never seen this. Makes 100% sense. I love learning new stuff after 45yrs in the business.

This goes even CRAZIER doing recording studios. We had to build a separate raised concrete slab on the concrete flooring and framed a wall outside the raised slab and on the edge of the raised slab. Essentially, we framed a raised floored room within another room. We then used kinetic isolation brackets from one of the internal studs slightly offset from the studs for the outside wall. Double layer both sides with a plywood backing layer in between them on the inside with foam insulation finished surface on the inside starting at 6' up to the doubke-layered floating ceiling that literally didn't touch the walls with a half inch gap that got insulated before caulking with cp506. We were told we'd probably never do work like that again in our whole career because almost no one cares about noise isolation as intense as the client did for their 8 recording studios.

If I was doing my own home, that staggered stud framing in the video is what I'd be doing.

Then the HVAC guys come and run a single cold air return for both rooms

If there's any form of construction which you believe stops sound from transferring between rooms then you've clearly not met my kids.

Apartment builder: got it, don't stagger

[Dogsnark]

I used this method in a house I built many years ago. I wanted to prevent sounds from adjacent bedrooms to be attenuated as much as possible. It worked. But a builder has also to consider sound going through the ceiling. Good insulation in the space spanning the rooms is a must.

Wish the bathroom I have bordering the kitchen was like this. Nothing worse than hearing giggles at the dinner table while I’m taking a dump

[catalyst]

insulated interior walls alone makes a huge difference

[aikonomic]

All toilets and bathrooms need to have this.

[StefanMiller]

We used that on a professional recording studio. Works like a charm with rock wool insulation.

Our apartment complex was originally designed to be condos but the developers reconsidered the units to be apartments.
The GREAT thing about when it was built was that all the shared apartment walls were built with plywood on both sides of the walls.

This has been WONDERFUL as you NEVER hear your neighbors TV, music, etc.

Therefore NO noise complaints to the property management staff and no stress for the tenants.

Noise complaints are the top stressors for tenants and property management staff.

This should be incorporated into the apartment building codes.

Except for that blocking midway up the wall that is very likely hitting the rear studs. Then the trades come in, and put a non-acoustically sealed outlet or low voltage plate in the wall. Then the HVAC guys install a shared air supply to both rooms, with a return air in the same vicinity. And the doors are not solid core.

I am going to have my house built in 2 years and love watching these because it gives you GREAT IDEAS what to tell your contractors ahead of time👍 thank you.

[CarterOfTheWord]

I soooo needed this! Now all I have to do is reframe my entire house.

[A_DHomesCarpentry]

Awesome 👍
We used the staggered stud technique on the outside walls on a house we built right next to the highway. It also allows for more continuous insulation.

[thomaslgrice]

That's a good start. I demo'ed the walls of music listening rooms in a library that was built in 1953. The walls had independent framing, sheathed in chipboard, 2 ply drywall, and none of the walls were parallel which prevented standing waves. You really need mass and separation to soundproof. Walls were finished with a heavy wall covering that had a coarse burlap base. When I got to the building in 1992 they no longer had listening equipment because everyone had a stereo in their dorm room, but I did use the rooms for recording music.

[donaldshimkus]

If I'm not mistaken, that's called double envelope construction. I heard about this from a customer of mine some 40 years ago.

[johnalvitre]

I do this too but I go 24” on center per side or 12” in center for both sides. This reduces the wood by 2 2”x4” per 4 feet of run. More insulation on a staggered wall reduces sound that much more. I also run my insulation laterally to gain better edge to edge contact. It definitely works and I am actually doing one this month.
