Something else you can do--and the cost is minimal--is use dissimilar glass on your windows. In my double-pane windows, I had the window manufacturer use 5mm glass on the inside of the IGUs, and 3mm on the exterior. Why? Sound can pass through just about every material. But with glass, only certain frequencies will pass through the glass based on the thickness. So the audio frequencies that pass through 3mm glass, don't generally pass through 5mm glass. The result is when my windows are closed, the exterior noise that makes it into the home is attenuated about 30 dB. This makes the home that much quieter.

That is interesting. About the insulation, rockwool is better than foam in a very important way - Rockwool does not offgas like foam insulation does. Foam volatiles are harmful to health. Even behind sheetrock and paint, chemical foam vapors will end up in the house, and will for several years.

Home Depot guy said this standard practice

Sound proofing can be done by decoupling and absorption. The rockwool is pretty good at absorption but does nothing for decoupling. The sound hits the sheetrock, the sheetrock vibrates, the sheetrock is screwed to the studs, the studs vibrate, then the sheetrock on the other side vibrates, and the sound got through. Also of course holes, like outlets, particularly if they are in the same stud bay. There are ways to decouple that are reasonably good and cheap, and then there are ways to really decouple that are expensive. A tough point is to consider that the floor and ceiling also vibrate, then the joists vibrate and carry the sound under and over the wall as well as to the rooms above and below. I built a sound "proof" theater and the room is literally a box inside my house. If you took the roof off, you could pick the room up with a crane and drop it off somewhere else. It floats on special rubber blocks (silomer) and has its own walls and ceiling that are only attached to the floor system. There is a 1/16 inch air gap at the entry passage and an exterior solid core door attached to the theater room side wall. All of my electrical boxes are surface mount. I used a special sheetrock (quiet rock) that is laminated with layers of a special decoupling caulk like material that acts as multiple layers of decoupling. And you use a special caulk in between the sheets that is just an awful mess to apply (it sticks to everything). I then filled the stud bays with rockwool. It works quite well. Only the lowest frequencies get through (the sub woofer) and only if it is pretty loud. My bedroom is below the theater and my kids can watch movies in there and I can't hear it unless there are big sub-woofer explosions. Those sound like a thunderstorm that is 100 miles away and you are asking yourself if you are really hearing it. I have read that one of the best materials to use is sand. It is extremely good at both absorbing sound and decoupling. But it is quite the challenge to build a room that is completely surrounded by sand without any attachments to the structure around it. The first row of sand grains absorb the sound, vibrate, and then rub on the sand grains next to them, transferring only some of the vibration (decoupling) but also losing energy via friction (absorption). After a couple inches of that, the sound energy has essentially all been lost to friction heating of the sand.

That takes up a ton of interior space, BUT is a very effective way to accomplish sound isolation. A cheaper (both in cost and quality) is to use special sound isolating drywall 'hangers' off the stud, creating a 1/8" gap between the sheet of drywall and the studs, which supposedly does a great job with sound isolation. I am not certain but I believe Jeff Geerling used this technique, check his video on soundproofing is office (moving 5) if you are interested.

This is called a "staggered stud wall" and I've done this in my renovation. I used 150mm top and base plates with 100mm studs at 400mm centres each side (so a stud every 200mm). I can then weave acoustic insulation between them. I will also be doing a layer of OSB before the plasterboard without aligning the edges to further prevent acoustic penetration. I haven't finished it yet, so I can't speak to the effectiveness but my reasearch indicates it should be really good.

When we finished our basement we walled in the mechanicals using several methods to isolate sound to the mechanical room. The walls were 2x6 plates with 2x4 studs that alternated front/back - each side was 24" on center. So no mechanical coupling between wall surfaces aside from top/bottom plates. For mass-loaded vinyl a cheap alternative is ice-dam sheeting. We wove that through the studs, literally just hung and stuck (self-adhesive) to the studs. That formed a curtain of MLV inside the wall. On either side of that curtain went typical insulation, I forget which but it was a high-density fiberglass - shoulda gone rock-wool. Finally, the 5/8" sheetrock was hung on Z-channel - these are Z-profile metal strips that are screwed into the studs horizontally, and the sheetrock is screwed into them. This provides an isolation layer between the sheetrock and the studs, really reducing sound transmission. Instead of a direct connection from sheetrock-to-stud-to-sheetrock, all three elements are isolated and dampened. We built the door from scratch, mainly to make a 3" thick door. It was basically a sandwich, each door skin had a layer of ice-dam applied to the inner side. Inside the frame between the skins was a free-hanging double-layer of ice-dam (sticky side to stick-side). Between each skin and the inner curtain was pretty tightly packed high-density fiberglass. The frame had ice-dam on both sides, and the skins were glued (not nailed) to that. So through the outer edge of the door it went skin-icedam-glue-icedam-framewood-icedam-glue-icedam-skin. Overkill ? Yup. But dang, when that furnace and air handler clicked on, you had to strain to hear it from the finished room down there. I wish we could have done the flooring above, but it was already built. A buddy who built his house did a double subfloor ... The first layer was nailed to the joists as usual, but then there was a soft layer - literally a sponge-vinyl thing. Then the radiant floor heating subfloor layer, then the hardwood. The ceiling underneath was two layers of 1/2". The first layer screwed up to the joists as usual, then a special non-hardening adhesive (dunno which) and the second layer screwed only around the edges. The blobs of adhesive left maybe 1/4" between the sheetrock layers. High-heel dancing on the floor above and you could barely hear a click downstairs. Was awesome.

About a year ago, we refurbished a small apartment downstairs, using rockwool and double layers of sheeting, just like you mentioned. It’s been an incredible setup. Our tenants have hosted a few small parties, and I wasn’t even aware until the next day! Installing double sheets on the main walls and ceiling really made a difference. We also lowered the ceiling in the rental from 270 cm / (8.10 ish) to 240 cm packing it with rockwool and double sheeting for extra soundproofing.

Another great video. Thank you. And thanks to your other videos I’m using Rockwool and 5/8 drywall everywhere in a new apartment remodel. I’d rather lean towards being “too quiet” than not quiet enough.

Rockwool is good. I live in an old 1835 house that's been turned in to apartments. We're at the top of the house and have the whole loft space as our apartment, and there's two apartments below us. Right after buying we discovered the sound just traveled through the house, when people downstairs were talking in their apartments it was like they were in the next room with the door open. Could hear everything. Since we were taking the floorboards up to rewire we took the time to put 150mm of 45kg/m3 rockwool in the floor. It was a difficult space to soundproof because a large section of floor is not accessible due to the eves being boxed in, so I figured some sound would get up around the insulation. But we were careful to insulate as much as we could access and not have any gaps. It's a lot quieter now, and the voices we hear are very muffled, it's rare I even understand one word. So it's comfortable enough to live in with our neighbours generating reasonable amounts of noise and we all have our privacy now. In a new build or more intensive refurbishment I'm sure you could do better, but this is good enough for us. We've found it works very well for voices, TV, music. It doesn't work for anything that shakes the fabric of the house however, so we hear the snaps of the pull cord lightswitches downstairs the same as ever. Also, we have found some areas of this old house leak sound. In one flat our neighbours below have a fireplace and if they're next to it their voices travel up better. Thankfully they don't tend to talk loudly right next to it, but it's an example of how sound can travel around. As always ymmv, but it has worked nicely for us.

Great video 🙂 I learnt an acronym for noise treatment (specifically transmitted noise) many years ago: MADD, or Mass, Absorption, Decoupling and Damping. More mass reduces noise because it has more momentum and it takes more energy to get it moving/vibrating. Especially good at attenuating high frequencies with their shorter wavelengths. Absorption converts the acoustic energy into heat by creating a complex path for the sound energy to traverse. Open cell foam, rockwool, fibreglass wool all work well. Different materials absorb different frequencies, and often the thickness affects how much it attenuates, not the density. Closed cell foam doesn't work well because the "bubbles" compress and expand like little springs, transmitting the energy to neighbouring cells. Decoupling physically separates transmissive surfaces, minimising transmission very effectively. There is another comment from apostolakisl that describes it very well. Damping is similar to absorption, in that it converts the energy into heat, but the method is different. Damping introduces a flexible interface between hard surfaces to minimise transmission. An example would be to fix drywall to the studs using a flexible silicone adhesive and no screws at all, so that the vibration of the drywall sheet isn't transmitted to the underlying studs. On flooring, it could be laying something like rubber matting or styrofoam sheeting between the subfloor and the final floor treatment.

This episode, hands down, is my favorite! 100%, one day, when I build I'll be planning forthis and using these materials. Too bad you're not in the Seattle area!

Great experiment! You got me into rockwool, and I've been installing it while renovating my house--big improvement on road noise. I second the resilient channel, though, since that's the only thing that will truly decouple vibrating ceilings and walls from framing.

this was a good one just for the exposure of new techniques and materials

All the interior walls of my pre-war apartment in NYC are 1/2" celotex soundboard "lathe" nailed to both sides of studs, finished with 3/4" thick scratch coat and plaster. So quiet.

Love seeing this and definitely a fan, I've used some of your ideas in my house and I own a recording studio. Roxul is a solid choice for sound reduction, it works by creating friction with the sound waves (air) and slowing down the waves aka deadening the sound, In a recording studio or theater you typically don't cover it in sheet rock, usually fabric covered and other tricks to treat a room for sound specifically. Additionally, to isolate sound, you need mass in between, studios typically have an airlock and double wall though it depends on the studio, some have come up with really creative ideas to isolate sound. As far as spray foam it doesn't do much for sound unless it seals the air between rooms and it can potentially be toxic with isocyanates during the application and after if not fully reacted or in a fire also releases toxic gas. Roxul is mineral based and is nearly inflammable. Spray foam does have it's applications, I'd suggest air sealing with duct seal caulk and using roxul for the most eco friendly and best sound absorption. When you install sheetrock, you can also use RC channel and that can help reduce sound even though the sheet rock is reflective, there are also special sheet rocks at most sheet rock suppliers but not big box stores, they are typically sandwiched layers and thicker (more mass) Matt you should check out gearspace builds for commercial recording studios, there's alot of detail work that goes into a studio that could potentially help improve your builds : )

Compared to the old way, which was just empty cavities, now hear barely anything from showers etc like we did before in the kitchen. I do wish I went 5/8 drywall though, never even though about it.

Did you use slats instead of hat sections on the bottom of your I-joists to screw the drywall to? Did you glue your drywall to the slats or I-joists?

A house I worked on years ago was framed with 2x6 top and bottom plates with offset 2x4 studs. We had to almost yell at each other to communicate after the Sheetrock was up to hear each other during the final phases of construction.

My house is built the same and I did the Alexa thing. I put it in their light switch so I could make announcements and have a routine that slowly turn the lights on for them in the morning so they can get ready for school.

Keep up the great content Matt

Rockwool does fine for absorbing treble frequencies, but as you heard, it's the bass frequencies that are transmitted by studs or floor joists. These structural members act like the hammer, anvil, and stirrup bones in your ear to directly transmit vibrations. Decoupling those walls does wonders. Staggered studs are good, and double studs with a half inch space between them are even better. Dynamat has some products that target floors and walls to deaden sound transmission as well. I knew someone who had a home theater room with an 18" subwoofer in the room above his master bedroom, and we could go up there and listen to an action film while his wife was asleep right below us. It was remarkable how silent that bedroom was while T-Rex was stomping around in the room above.

Can we get a short video on how your energy bills compare from the old leaky house to the real rebuild house since they were similar in size? Aside from the clear benefits to a healthier and quieter space, trying to get a better picture of how the higher build costs eventually trickle down into the lower monthly energy costs. I'd love to hear a nerd talk on avg energy usage and how increased air tightness and the processes followed in the real rebuild series translate in real dollars. Yes you will spend more initially but research/the findings say you should save x% all things being equal. We're going to start construction with a lot of these principles called out specifically because they are presented in a clear and honest framework that I and likely others appreciate!

Last I checked it was not available in the US except through special orders via dealers. Basically cost prohibitive to get it in the US, but I've heard good things about it.

I'm surprised you didn't go with the mass loaded vinyl - would love to see the difference in sound.

And then there is the problem of being too quiet, or, spaces which have no outside "natural environment of sound" that is desirable but rather a sound problem around no sound. I would suggest folks who want to insulate for sound be careful. It seems easy enough to still get frequencies one would not like to hear in an otherwise quiet space. I say this because with various mechanicals in or near the space it is sometimes not a blessing to have the space be so contained, hence, the need for white noise. For example, I live in a place that has some good outdoor sounds, particularly in the mornings and evenings. I have often thought would it not be smarter to capture some of those live sounds and have them be in my living space? This could be a subtle mic and speaker setup where those live ambient sounds good be filtered in but not give the impression of amplification. Muffling what otherwise might be healthy to hear outside in a closed off space is not an awesome solution. I think we have all heard from time to time a bird probably near an exhaust duct and wondering if the sound as it traveled say into the bathroom could not actually be taken advantage of more. Food for thought. All in all so much attention is being given to sealing up spaces but with fresh air being mechanically delivered that the other component to comfort is actually having a living space and not a dead one.

Echo reduction requires soft materials INSIDE the room. Use carpet, use soft furniture, put soft objects in the room corners. Find soft art objects to put on an expanse of wall, or a decorative slatted treatment on a section of wall to break up the expanse of completely flat surface. If you want to address the huge expanse of ceiling that is causing sound reflections, you could look at a drop ceiling of acoustical tiles (if you can find something that isn't too ugly for you), or various KZread channels on home production studios show how to make boxes out of acoustical material that you can hang from the ceiling to break up the sound reflective surface.

That floor is much better than you think it is because you did the test wrong. All that sound that followed you down the steps also followed you to the kitchen. So when you measured the sound, the device picked up the noise that bypassed the floor. To accurately measure the floor, you need to first temporarily stop the noise from coming through the door of the room upstairs and down the steps. Also, those sound measuring apps are poor guesstimates at most. It’s best to measure with a device designed for measuring sound. If everything would’ve been measured correctly it would’ve shown very little noise coming through that floor.

Sound deadening a home "sounds" pretty complicated. When you're living in a home and all your furniture is in, sound transmission is pretty important. I notice on new home tours sound reflectance, especially in a 2 story foyer + great room combo is an annoyance to me (the narrator's voice starts sounding hollow).. Of course the ultimate is to design like a concert hall, but then the home would be soo expensive... I would think using 5/8 sheet rock and rock wool would be sufficient for most rooms and additional wall treatment for sound reflectance in the home theater room would be enough. Double or triple glazed windows if your neighborhood is noisy ? Speakers with push-to-talk to prevent accidental sound transmission from a room would be better than an Alexis controlled speakers to ensure privacy.

If you have an open air attic, crawl space, basement above or below you can put rockwool in there.

You can cut a bunch of round holes on drywall and blow in insulation. You can then patch holes and putty coat entire walls or add a second layer of drywall over it (easier on ceilings because they don't have doors and casings to account for wall thickness.) The 2nd layer can be 5/8" drywall and it can be done on only one side of interior walls. Or remove drywall add batt insulation, install hat channel or RZ channel and install new 5/8' drywall. Swap hollow doors for solid doors with weather stripping.

Vote on adding a voice assistant in every room. I did with my rental. And I don’t ever shout anymore. Just announce it and they’ll come

Have you ever seen active noise cancellation technology for a house?

Go with Nest speakers and you can just say "Hey Google, broadcast".

Love that your daughter has a poster that says "These Colors Don't Run They Reload".

Matt, really disappointed with the testing. Was hoping to see you do a comparison of rooms next to each other like bedroom -> bedroom. Or like where you started the video at, Family Room -> Bedroom. I understand comparing 1st floor to 2nd floor. But not all homes are 2 stories. I remember in your “Real Rebuild” series you caulked and went to great lengths to “sound proof” the shared walls between bedrooms. THAT would be a better test comparison.

I always found that Matt’s sound “tests” to be lacking.

Suggest how I can do them better. I’m always open for a good upgrade

Great product but don’t count on it to take care of all your noise problems, i’d still recommend resilient channels, etc

Hat channels would do absolutely nothing but lose you 7/8" ceiling height. Resilient channels are FAR superior for sound attenuation, and cheaper and quicker to install too.

Honestly for the amount of money you spent on this house you should be ashamed for not including sound resistance doors or some sort of hidden hidden acoustical door sweep

I say on point your "On the build show" phrase in unison with you

You'll hear every drop of rain with that spray foam roof though

So what about when the house is already built and your POS builder didn't put this in

Another thing you can do is buy soft ear plugs.

Right, add Alexas, so all Amazon IT dudes can listen to you :-)))

The thing I didn’t see here was a calibrated sound meter (or SPL meter). Testing using your phone isn’t accurate.

Do you need that level of accuracy if your demonstration rounds to the nearest 5 decibels? Use the right tool for the job, you don’t use micrometers to place studs.

This really didn't show anything (not to be rude, but maybe you adjust and show it in a future video!). As soon as you move away from the speaker, your sound meter drops. Try it in the hall with the door open. There's basically no soundproofing with that gap under the door. It's like heating (cooling in the south) a house with a window open. Funny enough, 1/2" drywall can be better in some cases (with 24" OC) because the flex of the wall can be absorptive. Proper soundproofing needs decoupling like clips and channel (not resilient channel!). It's a complex subject and requires quite a bit more than extra insulation. Mass loaded vinyl will do nothing. To increase mass you'd use double drywall with a constrained layer damping compound (eg Green Glue). One last note, soundproofing is keeping sound in or out, not to be confused with acoustic treatment which is controlling the quality of the sound in the room. They are separate and you can have one without the other. Drywall is very reflective and almost all drywall rooms benefit from absorption to reduce reverb. Living spaces often have some via furniture (but need more) while a room like a garage sounds horrible without acoustic treatment.

When are we gonna hear the tips? Was the noise reduction so successful and that's why we couldn't hear them?

One thing that I noticed in the US, was that the interior doors do not have gaskets all around the door as you would see in Europe and Asia. This really helps a lot reduce sound penetration. Is there a reason that is not done in the US? Just a cost thing?

Lost count how many times he plugged USG Drywall. There should be a disclosure if you’re getting a kickback for pushing a product. I personally don’t see anything special about USG brand.

I love your shows and ideas and believe that perfection should always be strived for in life but in regard to your videos these standards are untenable for the mass of population mostly because of cost thus most structures, especially homes, are built on minimal standards to keep the cost low. Your house in AZ would be a million-dollar house. Really? Nice for those that can but it sucks for the rest of us.

The more sound abatement you do, the cost goes up. Remember you are building a home, not an audio recording studio. 🙂

Что за регион у вас, в сочи что ли? С такой входной дверью в сибири опухли бы коммуналку платить

hi matt, all you have to do to get the kids downstairs is to put the internet on a room to room circuit and turn it off in their bedrooms. trust me they will be down before you could shout "come down"

It’s only $50 Sq.Ft. !!!! So adding $5,000 a room is extra cheap for most of us.

I bet if you use the pink Owens Corning with 5/8 “ drywall it would be just as quiet but way cheaper.

Speaking from experience at my house, I gutted it and removed pink fiberglass and used Rockwool when I re insulated between rooms and it made a massive difference. So I’d bet against you on the just as quiet part but not the cost part.

Rockwool is more dense, therefore stops more sound.

@TheChipMcDonald

​​@@suspicionofdeceit It's not significantly denser, or dense to stop sound. It's preferred over fiberglass in an open face use because of a slightly wider bandwidth of absorption and for less concern over inhaling fibers (questionable). Rock wool being more dense *in a wall* will help transmit low frequencies. There is an optimal density to reduce sound transmission, fiberglass would probably be better than having rockwool packed in tight like shown in the first house.

mineral wool doesn’t offer any advantage once the drywall is up. In fact if you do real research, it actually performs worse than fiberglass. None of your bubba viewers would ever comprehend the data, however. Oh well. Waste your money!

it is always quiet when no noise is being generated

What the heck. Why can’t I speed up the playback speed

80db isn’t even loud, especially for a young kid. Try 120db
