I built a micro (9x9 foot) studio / office in my detached garage using 1/2 inch homasote screwed into studs and an additional 1/2 inch moisture resistant drywall screwed into the homasote using laminate screws with no laminate screw contact to wood to break the sound..(I researched other options, including a European sound breaking screw attachment system and also locally sourced drywall suspension channels which decrease the office space so I settled on drywall over homasote due to space limitations)...a flexible adhesive was applied to further connect the drywall to the homasote. There is a vapor retarder as well for moisture control given my situation in my climate and structure. Gaps were filled with flexible acoustic caulking or fire caulking depending on the situation. Stud bays were filled with rockwool. Area above the ceiling was capped with more than R60 total of rockwool covering truss lumber and even more fiberglass (layed crisscross and fiberglass over rockwool). Sound is considerably mitigated inside to out and outside to in for most frequencies accept for the lowest rumblings, which are very infrequent (neighbor mowing). Interior has acoustic treatment to lower resonance and echos. Bass trapping will be unrealistic in this small space. The floor is over 4 inches thick and includes laminate over plywood subfloor over pink high density foam insulation over vapor retardant OSB subfloor with little feet over concrete (we are in Minnesota....cold in winter). Floor has a rug. Final sound mitigation will be a hanging "sound blanket" over exterior of insulated steel entrance door to office as that is the prooven source of any major sound contamination in or out. I have difficulty hearing hail and rain storms plummeting my garage where the office is located. Anyone can do this sort of sound mitigation on the relative cheap.

Here in Australia, there is a company that makes high-density walling material called "Gyprock Soundchek". From all accounts it's quite effective. There may well be similar products available in the States. There is also a recommended procedure of laying out the stud wall before fitting.

Good shout, mate.

Not sure I agree here, a sheet of plywood on its own as you describe in air does have a different sound when hit compared to sheetrock however when 3/4 plywood is securely attached to a brick or block wall ie: an immovable surface, then that does not hold up, my research says they are sonically very similar and venner plywood is aesthetically more pleasing, well to me anyway. For soundproofing sheetrock is denser so its mass wins.

I agree, once secured to the wall studs plywood is going to be as damping as sheetrock. In my basement, I’ve used 1 1/2 inch thick barnboard over the existing plywood walls. It looks great and the room sounds amazing.

I built a small dedicated sound room in my basement, but only drywalled the outside of the walls and used fire resistant fabric on the inside and ceiling. There are no hard surfaces inside except the floor which I partially carpeted. Then I've added some pictures and other decorations to add back a little reflectivity. It sounds great to my ears.

Personally I would go for Rockwool in a battened frame, covered with fabric for most average sized rooms.

Heard that some use what is called viscoelastic glue between layers of drywall. Sould increase the damping effect quite much. Basically a rubber glue that don't fully harden. Liquid Rubber HB S-200

Sonopan; best sound absorbing material!

Decoupling drywall can be done with strips of rubber on the stud face but the most effective way is a metal Z channel that horizonal to the studs. I've never seen 3/4" drywall but typically two to three layers of 5/8" drywall is used in studios.

I live in a sleepout, and all the walls are plywood. I didn't realise how much they affected my sound until I put Blu Tack all around the power points. The difference was huge! So much cleaner now.

@@stephanespohr886 Yes, on the wall all around the power outlets to your stereo and TV. You can also use it on shelves supporting your equipment. You can put it underneath the eq so it won't be visible.

Check out Robert Harley’s article in The Absolute Sound where he describes how he built his dedicated listening room. Very interesting stuff!

Great idea. It would be easy to stick a strip of dense foam pad on all the studs and then just install the first layer of dry wall. Then glue the next layer of drywall using some kind of adhesive that stays pliable. Like the stuff you might put under flooring. That double layer of dampened dry wall would not be resonant. I'd love to build a room like this with rockwool insulation to isolate the listening room from the rest of the house.

On our yacht we used Canadian sequoia but it ain't cheap.

you can use a compressed paper used for flooring noise isolation on the dryer wall/ plasterboard struts, just use some contact adhesive just cut it to the width of the struts they come in sheets.

Vicoustic Wavewood Diffuser Ultra ♥️

They make rubber beam/stud isolators that can be installed onto the face of a 2x4/2x6 stud (16" on center). They help isolate the stud from whatever thickness sheet rock that you are installing.. #justsayin

You may be referencing resilient sound isolation clips (RSIC) for mounting the drywall to the studs. When I was building my home theater I looked into those kind of things, but it really would add cost to my modest project. I also looked at the z-channel referenced in the comments. Any of the solutions to "soundproofing" rooms would have added cost and complexity beyond what I really needed. I used rockwool and 1/2" drywall attached to 2x6 studded walls against concrete with the ceiling above a dropped ceiling packed with 12" of insulation. It worked fine except when the kids were watching the movie "Master and Commander" at a volume I'm sure my neighbors 100 feet away could hear inside their house.

When using multiple layers of drywall, make sure none of the seams of the second layer line up with the layer beneath. They should all be covered by the second layer. It will be more work, but there will be less bleed to the rest of the building.

I have concrete walls everywhere. Pretty good

that all light material all vibrate... brick and concrete is the only way.. also floors.

I had to deaden some small booths for audio testing of devices and the local "foam warehouse" also has rolls of various materials; I picked up a roll of this odd vinyl material that was recommended by the shop for not too much but for being not even 1/4" thick it was downright magical in killing both high and low vibrations, just sucked em up like a sponge. One of the oddest materials I've ever worked with and really was an ace up my sleeve come review time. ;-) I never even learned if it had a name or what it was called, it was just "deadening" material and boy engineered materials can surprise the heck out of ya sometimes; it's like someone designed it to do a specific thing and it happens to do that thing well. And the booths had sliding glass doors to get inside them - double sided sticky tape and plastered it on there, problem solved! 🙂 Then again glass isn't quite as resonant as wood when it comes to signal regeneration, if you get the right frequencies wood will erupt with all sorts of second and third order effects (glass has no internal structure as well as being really dense). But glass reflects like mad, so you've gotta trap it to keep it from scattering everywhere...

a listening space is a component of the speakers. when contemplating devising a home near-field (especially) listening room, in addition to determining your listening position, consider the interior of a well-designed / engineered speaker ; volume, shape, hwd ratio, structural material, surfaces, objects, damping materials & the like. what are their damping / absorption & reflective characteristics? room modes @ different freq? address these factors (in concert w/ with the spkr's own signature) & you may achieve a very satisfying soundfield w/ a tuned / tunable nature... & it's fun!

Love your vids! However I've researched that ply is great for absorbing and dissipating sound better because of it's multiple layers. So construct your soundproofing with two layers of floating drywall and a thick as you can ply for your acoustic treatments. Any thoughts?

Plywood can make a great auditorium. Lively though.

Use a heavy burlap type wallpaper.

Burlap itself won't do that much, it should also have at least an inch of fiberglass behind it to deaden the room. I've heard rooms with just burlap and they were still quite active. Burlap can be flammable if untreated, so be careful. Personally, I'd find a different fabric if going that route.

look at alt stud spacing and add an air gap as well.

Use brick and concrete you can't go wrong. That's what I used.

I was thinking of using my basement to set up a listening space but it is unfinished. The advantage is that it is big so I can place the speakers away from walls which I can't do as easily on my first floor. Would this work well? Regular basement walls but speakers placed optimally away from both front and side walls?

You would want to cover the concrete walls to lesson reflection. Floor would need carpeting.

Paul, what about noise dampening insulation like rockwool to insulate the walls?

What about thicker laminated plywood or birch plywood. Speaker boxes are made with this and are rather dull especially for their thickness & Weight

How about cork as wall material?

Use two Dry-wall sheets glued together with green acoustic adhesive works very well. Also look into bass traps for corners. Hanging ceiling panels and the flooring is critical as well. Many recording studios actually isolate the building frame to limit transmission of noise/sound in and out of the studio. Professional recording studios cost a fortune because of the expensive acoustic materials used and the complicated building and construction techniques needed. Usually acoustic engineers and consultants are involve when converting an existing building into a professional recording or listening room. It's always better when starting from a block of land and purpose building a studio from the ground up (but most people, even businesses dont have that luxury). Good luck. (There are cheap ways to transform a room, attic, basement etc into an acceptable acoustically treated recording and listening area, but you will need to make afew compromises with a certain things during the build.)

As a DIY speaker designer and fan of PS Audio, how does the future of speaker design look for someone trying to break into the industry? Ive noticed that a lot of more impactful newer hifi releases come from collaborations between legacy designers and audio giants, extreme high-cost systems, or re-introduction of old design ethos'. Where is the next phase of grassroots speaker design coming from?

What about plaster. It’s said that it is sound deadening vs. Drywall sheet rock which will echo. I us

never seen a speaker lined with drywall

I would think non parallel long walls would help to, but not an acoustic engineer, so just a guess.

It’s hard to tell sometimes a little vibration is good

Cork .....?

Cork doesn't burn.

fill the walls with sand

By that rational speakers should be made from dry wall rather than mdf/birch ply? - maybe the new FR100 will have fully drywall constructed cabinets 😂

I'd like to try sheathing a room with 3/8 OSB covered by either spray foam (the catalyzed stuff, not the stuff in a can) or cellulose. Perhaps spray painted with an airless. It would be a wildly rough texture and probably intolerable by most people but would be the ultimate in diffusion.
