But you didn't learn how to build a diffuser. Do a little research first. The blocks shouldn't be random - must follow a specific pattern or it won't work.
A few thoughts/tips/suggestions for you. First, instead of "random", you can use a program like QRDUDE to help you with the depth of blocks and order they go in. Second, the smaller blocks will diffuse better in frequencies that are important for studios. Second Part 2 - the depth (height of blocks) and size of the overall diffuser determines the lowest frequency you can diffuse; smaller individual blocks will diffuse higher frequencies (no less than 1" x 1"). Also, you can lighten up the overall project by breaking it up into quadrants, and/or using a good forstner bit to hollow out the blocks before you glue them to the backing plate. Finally, you'll need a LOT of diffusers to have a really big impact...but I'm betting you'll get a notable improvement if you build at least two more of that size (especially if you use 2 x 2 blocks with greater depth). I hope that helps out some!
This guy is right, but maybe too polite to get his point across. You screwed up bad. I'm surprised someone would make a video about building a skyline diffuser without knowing what a skyline diffuser is. Those blocks ARE NOT random. Some serious math goes into these so that they will diffuse sound and if you don't get the sizes and pattern right, it won't work. You made the equivalent of putting a Ferrari body on top of a '96 Honda Civic - looks close, but not right.
Props to the build, only thing if I can add. If your doing more panels, the wood floor glue that comes in buckets would be easier to trowel/roll out for faster times but I also agree with a hot day that goes against you.
awesome. do you like these bigger 4x4 diffusers better than the 2x2's? Also, I was thinking about doing this but making a slight angled cut...maybe like 10 - 20° on the miter saw and have each piece slanted a random direction. would this further help sound dispersing?
The main thing I learned after making a diffuser with smaller pieces is that it takes SO MANY pieces at that size, so I went with the 4x4 size to get a larger diffuser without having to cut hundreds more pieces. They take a little bit of sanding, so each piece adds up in production time. I've seen some diffusers that have an angle on the pieces like you mentioned, and they look nice, but the diffusion would be less predictable. Mine is random, but for maximum audio benefit, it is recommended to use a diffuser calculator that says the exact height for each piece.
Hi great video! Im thinking in build some diffuser panels, and i have a couple of questions, do you think if I paint them (in black) will affect the result? there is a pattern to place the different length wood pieces? Thanks in advance, Luis
The paint shouldn't affect the result. You can find a calculator here to tell you what size to make the pieces on the skyline diffuser. There are a few of them under the "Diffusors" section: www.mh-audio.nl/Acoustics.html
Looks very good! I like the larger blocks, too. Much easier than all the small ones! I also like your idea of hiding mounting hardware behind some blocks. Wish I had thought of that when I made my abstract piece last year!
Thanks Sam! I thought long and hard about how to mount that on the wall. I recently watched your abstract piece video. I like how the colors have a drip effect.
Building panel like this without acoustic diffuser calculator are not very effective way. "Normal" echo damping can be reached more easy way (massive HDF or fiberglass plate coated with something soft work nice). Calculated skyline usually used for room correction, but they look cool.
@@BobsWoodStuff yeah, nah. It’s just after that and just after you flipped the blocks. We all heard it, Bob. Just make sure you bring enough for everyone next time. 😄
I did one! However I posted it online and people hated it and said it won't do low frequencies because it's too shallow and I need a true quadratic diffuser. I haven't used it yet. Have you notice if it works or not?
The variation in sizes is what makes this design work. When the sound waves hit the different surfaces, they get randomized, so you get a natural sounding reflection, without hard echoes like a flat wall. It doesn't absorb like acoustic foam does, it is a different effect. I tried to make the size of the pieces random, but for best results you can plan the exact size and placement of the pieces using a calculator like this one: mh-audio.nl/Acoustics/DiffusorCalculator3.asp?km=7.5&kl=100&calc=Calculate+Diffuser#result
@@audiowolfnet9347 In my case it is mostly for decoration, but it does mellow out the sound from that wall a little bit. On two of the other walls (not pictured) I am hanging moving blankets to soundproof the room, and I have some foam in the corners.

I appreciate your concern. Are you talking about the table saw or the miter saw? Sometimes the camera angle or the fast forwarding can make the blade look closer than it is. There were a couple spots on the miter saw where I probably could/should have used a clamp.
@@BobsWoodStuff Table saw. Isn't it good practice to use another sacrificial piece of wood in between your hand and the piece being cut? I know you were being careful, but you only get one chance with those blades. Extra caution is advisable. Good luck, nice video.
@@Coneman3 Thanks. I am using a wooden push stick in my right hand once the board is all the way on the table, which is the correct way to control the board. The questionable thing I am doing is grabbing the waste piece with my left hand once it has separated. This is pretty easy to do on a smaller table saw like a contractor or jobsite saw like mine, but I would not recommend it on a larger table saw.
I used Douglas fir 4x4s, untreated. I don't recommend treated lumber for indoor use. Redwood or cedar are for outdoor use, but can also be used indoors, so if they don't have any fir or pine, you could look for redwood or cedar.

Kind of a bs video. The thumbnail implies you are making a curved peice that could fit in a corner. Also unless you use a mathematical formula then you "diffuser" will do very little if anything at all. Also that part where you planed the edges after glue I see you quickly realized that's a very bad idea as you are almost certainly coming to tear out the edges doing that.
This is damn wrong made. You cannot placed blocks randomly, everything must be measured. High, width, and every single position. This diffuser doesn't work.
