I don't know why this is continually overlooked but in pro installations (movie theaters) they simply use indoor/outdoor carpeting as wallpaper to damp reflected sound.

In an empty room (or entire house) I would first bring in all the furnishings, couches, chairs, rugs, curtains, book shelves, all these will dramatically change the acoustic dynamics and properties of said room, THEN reevaluate, then start bringing in the absorbers, diffusers, bass traps etc.

My neighbor has a ghetto studio. And has curtains on his wall with sound absorbing material I’m assuming. So when he records he closes the curtains

I moved into a new house, it has a great room with a vaulted ceiling. We unpacked our stuff & untidily stacked the room up clothes, bedding & mainly soft furnishings. I hurridly set up the hi-fi, and it sounded fantastic. Later, once the room had been cleared of clutter, it was though someone had been in and stolen the system, and switched the speakers for a pair of biscuit tins.

Really not. I have some problems with noise from motobike kids. Made few heavy bass-dampering panels and sleep well now.

I totally agree with the rug assessment. After wrapping most of the 3 walls with heavy drapes, I found a huge used carpet with pad. Immediately had huge improvement.

GREAT VIDEO, Ron - and you're absolutely right, acoustically treating the room is soo important and it's often neglected. I took my own sound system to a completely different level when I began experimenting with some modest treatments a couple years back, and those room treatments I now consider the second most important hi-fi purchase I ever made (second only to the speakers themselves).

Killer installment, Ron! Thanks for offering up such a continually varied, wide ranging, interesting set of topics. Best of KZread, I’d subscribe again if I could 😂

I love this video! I build a lot of studios here in LA and having panels with an air gap (being able to get the panel off the wall) is a big helper for getting effective absorption. The way I do it is instead of building a frame AROUND the insulation, build it to fit the back and use a 2" wide piece of wood. So that way when you wrap the fabric, you wrap it around that piece as well and so when you mount the thing on the wall, you end up with a nice 2" air gap behind it, but it looks mounted directly to the wall.

Thanks for pointing light into this much anticipated topic Ron. Long awaited.

We have tile throughout our house. First thing we did to knock the echo down a couple of notches... Put in a moderately thick wool rug area rug and several pieces of furniture. We also have some huge windows and a sliding glass door, so we put curtains up. Been thinking about the art covered GIK panels next, and probably a pair of bass traps. Will have to try a rug pad now that you've mentioned it. FYI you can do french cleats to inexpensively hang things off walls. Just cut an angle on a rectangular pieces of plywood, one side goes on the wall, the other on the object to hang.

I hadn't thought about the need for a diffuser to scatter frequencies evenly. In studio settings it's common advice to place diffusers behind the listener, but I love the idea of putting it behind the speakers and side first reflections. Gonna have to play around with it. You've very quickly become my favorite audio KZreadr. Especially love the acoustics content. Awesome job.

My best Magnepan setup used 18 inch diameter sonotubes lined with 6 inch insulation and covered with light cloth to give them color. These were placed along the front wall six inched apart and on spikes that allowed sound to enter the top and bottom. Top and bottom were separated from ceiling and floor, again by six inched. The Magnepans were placed out into the room 5 feet from these. This room was 22' by 51' and sloped upward from speaker end. This scattered the rear wave and the soundstage was breathtaking. This supports the dipole recommendation on this excellent video.

Great video Ron! You nailed it this time. 👍

same experience for me, new room and even before considering treating the side walls putting a large shaggy carpet and a thick (non-leathery) sofa changed the room sound completely (specifically the room modes)

Great video, Ron. I found that pulling back my carpet away from my speakers and keeping it just several feet around my listening area improved the liveliness of my room. The large rug deadened the room too much. Test the rug - pull it back and forth and see what works best.

Excellent video, Ron. I could not agree more. One of the biggest improvements I made to my (small) listening area in last year, by far, was to put up some GIK Alpha 4A diffusor panels. GIK has great information on their website and also excellent, affordably-priced products. Cheers and thanks.

Too bad most people don't understand this. I see so many pictures on the web of expensive gear in rooms not treated. The biggest sin is speakers shoved up against a wall or not properly set up. They a missing the potential of what they could experience. I guess ignorance is bliss.

GIK sells “ Cloud Mounting Bracket’s” specifically for their panels. They work on the ceiling and walls and separate them from the wall quite a bit.

Great comprehensive video. Thanks.

Good video! For keeping panels out from walls, an ordinary right angle bracket will work. These are the kind that cabinet makers often use for attaching shelves. They can be found in any hardware store, and come in different sizes. One side to the wall, and the other to each of the four corners of the panel, if it has a wooden frame. I have also read in many places that if you put a panel in each of the four corners of a room and angled across the corner, it gives you a very large space behind the panel and helps the absorption immensely.

@kennethsrensen7706

Just remember that the Airgap may NOT exceed the thikness of your damping material , otherwise the gap being so big the effiency goes down. Example if your panels damping is 10 cm thick then your Airgap should NOT exceed 10 cm . so if you have a 5 cm thick damping material and a 10 cm airgap you actually make the absorbtion worse . The optimal is 10 to 8 so if have 10 cm damping then go for 8 cm airgap . ( this refer to acoustic wall pannels as well as bass traps ) The rule of thumb is more mass equal more absorbtion in lower frequencies . And for shure you can use angle brackets , they work pretty damn good and cheap too : )

Great video Ron! I would start every video going forward mentioning room treatment is more important than the gear. 😉

Hi Ron, Thanks for taking the time to take this video! I'll definitely use it as a reference in the future! I have my own channel, but focusing on car audio, which has it's own challenges, if not not even more complex, than home audio. It's great to see your down to earth way of explaining things, similar to what i do kicking people to understand the importance of speaker locations, installation and tuning in a car. I'm just starting my home audio project too (as we have so much time now unfortunately) and planning to build my own 3way OB dipole speakers, so again it's nice to see that you have a sweet spot for those type of speakers. ;) Quick question though: is it still rare that people run their speakers fully active indoors?

Hey thanks man!

We just added Vant panels to our piano room. They sit 1” off the wall mounted on brackets, designed for headboard or office but look and work great for sound panels.

Hi Ron, I completely agree with all you have said however, I have found that another improvement in the room acoustics can be achieved by covering the wall behind the listening position with limp membrane sealed bass traps. I constructed mine using timber frames eight inches deep fixed onto an MDF back panel. I filled the frame with loft insulation leaving a one inch gap between the insulation and the front of the frame. I then used 2mm thick rubber sheet over the front and used beading to make an air tight seal between the rubber sheet and the frame. The improvement in the room acoustics is astonishing especially in the bass.

My current room has wall to wall carpet with a dense under-lament. Best decision ever. The wall cavities were also filled with some of the most dense wall insulation I could find (due to exterior room walls being super hard/dense and therefore Bass would go through sheet-rock, but then get reflected back into the room. So a very dense wall insulation makes for some good bass-absorption). Then 1st Reflections, plus some Bass absorption, and finally some scattering. The most I've ever spent on the Room vs. the equipment in the room, and simply worth every penny!!!

I have two big thick carpets on my side walls, this made a huge differens in our concrete room. From cold to warm, I think I put rug pad behind them future on. Big thanks for this video

Anders Forsgren yeah it's pretty disturbing when you visit the acoustic fields KZread channel. 10,000$ minimum and ideally 30' rooms.

Wall absorbers and bass traps are not the same thing. I never heard anyone say wall absorbers are for bass - they'd need to be a foot or two thick. A good manufacturer will tell you what frequency range a given panel is designed for (same goes for diffusers). Ultimately you need a combination of both. Also don't forget the ceiling. Best advice I got from a 75 year old sound engineer was you want a room that's 50:50, half dead, half live. I find this works, it doesn't even matter which half or if all the absorption is in one half and all the diffusion in the other, just half the surface area, however you want to arrange it.

I’ll just share this, which may apply more to musicians looking for soundproofing, but I suppose could be a budget thing for avid listeners who aren’t rich. On one music room, I took two 12’ 2x4’s, put one on one wall horizontally about at 7’ from the floor (use a stud finder, drill and screws) and , took the other one and did the same thing on the opposite wall. Now, measuring the distance from the walls to each other, cut two more long 2x4’s that then rested by their ends on the first two boards. Then took two more 2x4’s and rested them on the second two boards. I hung moving blankets (that had been folded twice and grommeted on one end into a long panel, giving four layers of blanket) up by taking two of these “panels” and nearly joining them together at the top with zip ties. They then hung over the 2x4 like a saddle over a horse. This gave me the ability to create a “booth” that could be as large as the room, or smaller of any size or rectangular shape and any place in the room. Eventually I just settled on them just off the walls. Surprisingly, the weight wasn’t much of a factor but there would be a hair of sag. So just took a roughly 7’ board and used it to support the boards in the middle which were covered by the panels. No nailing or anything just the weight would hold them in place.

Hey Ron and everyone. About distancing the panel from the wall. I constructed home-made panels that are similar to the ones you described for absorption. To distance them from the wall, I simply screwed a cork bottle cap in each corner of each panel. I found half of it makes a decent length but you could use the full cap I assume to make more distance. Hope it helps!

How did you end up attaching the panel to the wall?

Love the framed Lord Huron LP!

Room acoustics and quality loudspeakers with a proper set-up across the frequency band. That’s the foundation that will make even the mid market components sound great. Then you can chase DACs, turntables, gold vs silver and the other esoteric stuff to actually hear the improvements you’ve made instead of imaging what you hear through a colored sound full of phase distortion.

This is outstanding knowledge. Thank you.

Great video, very informative. Just one question, at the reflection points do you put a diffuser or absorption panel?

Even if I had the perfect room, amp, pre amp etc.. I’d still continue to buy and test speakers. Thats what it’s all about. I want to hear and experience new things. Keep the ears learning. I love it! Thanks bud!

Now I think I know why my budget stereo system sounds so good in my bedroom...my bed is like a giant sound absorbing panel that is stood off from the ground. The perfect blend of acoustics and comfort.

I make my own panels. I use 1x3 pine which really are .75x2.75. To attach them.to the walls I get wood strapping. The pieces are 1x2 which really are .75x~1.75. I make them whatever the with of the panels are...usually 2 ft wide. Screw them to the frames and then use 3m picture frame velcro (16 pound kind) to hold the panels to the wall at 4 separate points. Holds them no problem and spaces the panels off the wall about 1.5 inches.

Agree. Rug is number one and has the highest WAF.

Thanks Ron for another great video. My hifi is far from ideal setup. Due to kids playing around with my hifi, I’ve had to move my system to the bedroom. I have a Magnepan LRS speakers on each side of my bed, the speakers are about 3 1/2 foot from the wall and about 7 1/2 foot apart. The LRS are toeing in. At the foot end of my bed I have a Kallax shelf from Ikea with my system on it. I’d like to put up some panels but have no idea where to start. If my speakers are toeing in, do I still use the mirror to find the 1st and 2nd reflection point? I think defusers Behind the LRS and possibly cover the Kallax shelf may be a good start as I do have thick carpet in the room already. Thanks again

Quadratic diffusion, adsorption and proper speaker placement are all important tools for great sounding room’s. Having a big enough room to work with is also critical in the process.

Where'd you get the long gray diffuser with the falling blocks in it? I couldn't find it in any of your posted links. Is it designed mathematically?

Good info on room treatment. I might add that the material which the rug is made of is also significant for the sound. Natural materials like wool and cotton will sound better than synthetic stuff like nylon, polyester, etc. One can demonstrate this by holding a piece of cotton or wool about 4” from your ear. Then snap your fingers next to your ear and listen to how the snap sounds. Then do the same with a synthetic fabric. The snap will sound like a sharp snap with the natural material and will sound more like a splat with the synthetic. An easy way to demo this in your home is to lay several cotton towels on the floor of your music room. Listen to some music without then with the towels. It will sound much more natural with the towels. I learned this from Pascal Ravach from Mutineers Audio. Same applies for side wall panels.

Hey thanks!

I've made 5 Arqen panels for my listening room. They really work great, really opens up the room. I made mine from 1/2" x24" x 8' blue styrofoam insulation available at Lowes. You can cut it with a razor knife and a straight edge, or better yet there is now a special blade for cutting foam on a table saw. Use white carpenter's glue to assemble, then lightly sand to remove the gloss before painting with latex paint. I also have 12 bass traps in my room, 4, 2' x 6' in each corner, 4, 2' x 2' in each ceiling wall corner, and 4, 2' x 4' traps on the side, back and front ceiling wall interfaces. All traps are made from Owens Corning fiberglass, 4" thick. You don't need to make a frame for them, I just covered mine with an open weave burlap, and used hot melt glue to affix it at the back of the panel. Hot melt is great, if you screw up just pull off the burlap and glue again. To make them, lay your panel on a table.Then take thin wood about 4" x 6", (I used vinyl siding samples from Home Depot) drill a 1/8" hole in the center of 4 of these pieces and knot a 2' length of mason's string line through it. Place the 4 pieces about 4" or 5" in from the corners of the panel. From the back of the panel, push a piece of wire through the panel. Then hook the string to the wire and pull it through to the back. The strings should now be on top of the table when the panel is laid back down. Now, cut a piece of builder's paper (Home Depot) to the same size as the panel. This is our limp membrane, which allows the bass notes to be absorbed, without disturbing the highs. Place the paper on top of the panel and tack with glue. Cut your burlap or other open weave material oversize to allow it to be glued on the back of the panel. Now, flip the panel over and glue the burlap to the back, taking care to fold over the corners neatly. If you're anal like me, you can glue plastic drywall corner bead all around the edges of the fibreglass (for a slightly cleaner look) then cover with paper and material. To mount the panels at the ceiling/wall interface, at a 45 degree angle, I used 2 nails in the ceiling and 2 in the wall. I used a stretchy 1/8" elastic cord and made a 4" loop in it, and then tied it to the correct length of each string. The cord allows you to pull the cord over each nail, and then holds the panel tight against the wall and ceiling. Your room will now be drastically improved. Now goest thou, and do likewise.

Do we have to do speaker placement first by your lots trick or do the acoustic treatment first?

If you toe in your main speakers does that chance the first reflection mirror test method?

I was just waiting to see your going to mention rugs. It happened to me.

Ron - great video. Please allow me to share some of my personal acoustic thoughts from years of experimentation .... Measurements first: You can't manage what you can't measure plays a role here. At the very least measure frequency response (ideally a flat response is better) and reverb time (to avoid over dampening the room with things that absorb too much sound). I use Dayton Audio OmniMic which allows me to see the troubling frequencies so speaker placement and acoustic treatment placement experimentation can begin and note its affect. Often solving one problem frequency creates a new problem so it'll take patience to try and optimize speaker and acoustical treatment placement. Treatment strategy: for most domestic sized rooms absorption of low frequencies and reflection and or diffusion of mid to high frequencies works well. This avoids over dampening. The transition frequency range for most home rooms where sound waves transition to "beams" due to smaller wavelengths is about 300-500Hz so you'll need bass traps to work below this range and diffusion to work above it. Thickness matters: Too often manufacturers sell absorbers and diffusers that are too thin. And the reason you want them thick (at least 6") is so they don't act like a low-pass filter and only operate on some of the frequencies hitting it. You want the absorber or diffuser to work as broadband as possible so as not to skew the frequency range of its reflections and reflections of those reflections. For a diffuser, the depth of its slots or wells (for a QRD or Skyline type) determines its lowest frequency, so for example a 6.75" depth will work down to 500Hz as it is one-quarter of a 500Hz wavelength. Sitting distance from treatments: Normally you can sit much closer to an absorber than a diffuser which needs more space for the scattering to occur so the sound coalesces by the time you hear it. If you need to be close to a diffuser - say on the ceiling or side walls which are near your listening position - then choose a 2-dimensional one (diffuses both horizontally and vertically) so that only about half of the reflections are coming your way.

Hey Ron, May I know where to purchase the grey diffuser?
