I made Skyline Diffusors for my Living Room

- Want some of those neat looking diffusors for your room? Seeing the price of them, I think it's needless to say that a DIY solution is more viable if you're like me and enjoy working with wood.
Overall, I paid about 300€ for all the materials. When you buy ready made skyline diffusors out of wood, you'll pay about 170€ for one, and I made 8 of those. You do the math.
This of course requires you to have access to the power tools in the first place. You can do all of that by hand, but it will take even more time.
It was a really fun project and I hope you enjoyed it as well!
Let me know if you need something.

First of all: Great work, your diffusers are looking amasing!!! That the Clapping doesnt make a difference is OK because you have Diffusers and not Absorbers. Onely one thing : To have the most benefit from your Diffusers you schould bring the Sofa a little bit of the wall and lower the Diffusers because you ears are the point where the sound has to be diffused an they are sill straight at the naked wall.Also your surround sound would benefit from the didderent sfa position.
First of all, because of the depth of that diffuser, and the size of each well, it'll only diffuse frequencies between about 700hz and 4000hz.
That aside, I'm sure it did lots of things, it's just that what you're hearing are the problems from all of the other walls.
The diffuser is also placed above your listening position, so you won't get the most out of it. I understand that you might not be able to fit it directly behind your head, so consider moving it to the ceiling where you have early reflections, for example, or directly above your head (in the ceiling).
I'm not sure what you thought the diffusor would do. It does not prevent reverberation, it basically makes the room sound larger than it is, and breaks apart standing waves so that the sound is _better_ .
You'll notice this is you sweep a sine wave in the room. Some frequencies (many) will be heavily boosted by the room as they produce standing waves between the walls. But the diffuser will help to prevent this within the effective frequency range of that diffuser.
So, I'm sure this did a lot of good for your sound. Just that a clap does not tell the story.
(I'm an audio engineer, btw.)
I was so relieved when agreed with me at the end 😂
What you've made are 2d diffusors, which propagate sound both horizontally and vertically. There's a reason such diffusors are mounted usually on ceilings (skyline) so they can diffuse both horizontally and vertically from above, which turns into 90 deg offset of diffusion (left and right, front and back). When mounting such diffusors on a vertical wall you get reflections from the ceiling and floor. For vertical surfaces use slot or slat diffosors which are 1d (large panels with vertical slots in them). Those diffuse only in one plane (left and right or up and down, depending on orientation). I did the same as you did and then measured with a microphone and was not happy, since I created a sharp dip and a sharp peak between 1200Hz and 2800Hz. They look nice as decoration on the wall, but when I changed them with 1d diffusors the room opened quite a bit for sound. Nice vid, it's very time consuming to make those out of wood.
nice info
"As you can see it did absolutely nothing". This cracked me up. Great charisma!
This is so good. And so German :-) Love the fact that your workshop is the balcony of a high rise apartment.
You use what you have ;)
@@normanwink And he's got that high Rise. This man is a Champ. Norm keep it up baller.
Great video dude. My favorite part, "If you have children or a monkey..." Hilarious!
Really cool! Remember, diffusers don’t make it sound dead-they just make it sound better. It’s artwork regardless of the acoustics. I’m interested to see what else you do with the space
Exactly, it does even sound smoother to my ears as the diffuser only scatters the clap more randomly - so less fluttering
Quick question, is it useful to place them behind the speakers, i see that often.
@@CyberBeep_kenshi Only if they have a dipole radiation pattern. You should use absorbers behind most speakers.
@@bathynomusgiganteus2916 cheers, i find the whole subject so complex. I am far from stupid and had math, physics etc education, but acoustics feel like i missed an entire 4 year study.
@@CyberBeep_kenshi You don't need to know all the maths and engineering to learn the best practices thankfully. Ethan Winer's video on diffusion is still one of the best th-cam.com/video/vb30CICG68c/w-d-xo.html
This video is helpful as well
th-cam.com/video/pTOfXlxGtZk/w-d-xo.html
Thank you for you honesty and it does look cool .
Thanks as well ;)
Wow! That is impressive and i am lovin it. Lovely dog, too.
My girl advice: It will me the hell for clean up the dust on it ! haha !! (Sorry for my poor english, I'm frenchspeaker) It looks awesome anyway ! I like it !
Yeah that's super much work, true!
But it's alright :D
Not sure how i got here but i am glad I found your content! Great video!
The neighbours probably love you when you cut with that saw half a day on the balcony :-D
Great Job! Whether or not it works acoustically, it is a fantastic piece of sculpture and looks great!
Such countersinking! Joking aside great project and walkthrough... thank you.
Comparing your voice at the 0:54 second mark vs the end, I'd say it worked. The reverb is completely gone.
I was going to say the same thing. Different* reverb!
Diffusers aren't suppose to remove reverb. They only reflect the sound in different directions to make it sound more natural. You'd need an absorber for that like a foam pad. It sounds better because instead of the sounds reflecting of the same spot on the wall, it's being pushed all around the room in different ways.
Heard the same, was almost a bit surprised to hear no different in the clap, until I thought about it.
very good, looks superb nice video, well done
Hiii Norman! Glad to see you back on youtube!
I'm happy too! Also really glad to know that you're still around as well :D
I just like the video cuz the amount of work it took
Mega geworden, könnte ich glatt nachbauen
Exactly what I was going to make. Thanks for sharing your project.
Beautiful ! Unpractical ? Who cares, its amazing !
Nice job.
very important experience .. I was planning to do it for my studio .. but it looks very nice as a decoration .. thanks a lot
Your neighbours probably love you after a whole afternoon of cutting wood on your balcony ;)
At least I'm not that guy with the hammer drill ;)
We live in a huge apartment complex with over 200 apartments... it rarely passes a weekend without someone making some construction noise
@@normanwink Haha yeah people with hammer drill is the worst :D
I wouldn't mind if someone was cutting wood on their balcony as long as my balcony don't get all dusty and it's not in the middle of the night. The noise for me is the least problem there has to hell of a noise for me to react. Are people that sensitive to noise?
Also I think, as a home theatre enthusiast, if you hear someone making noise, playing loud music etc. I feel it's almost my right to also play loud when I listen. So it's give and take or eye for an eye. For me it's that simple.
@@normanwink no worries. when I was still living in a bigger apartment complex I would regularly bbq and party on my balcony. Obviously my neighbours hated that ;)
The flat panels you didn't know the name of is called OSB here in north America. Stands for Oriented Strand Board. I hope this helps! Looks great!
It's called OSB in Europe too. :)
We say OSB in Germany too.
And in Russia those are OSB boards. Workers of the World, unite! ^_^
Hey, thanks so much. I have the same problem as you and was considering the same wood diffuser solution. Thanks for your honesty in how it didn’t provide the audio solution, you have saved me time and effort in building. It does still look really cool but I am looking for something to help with the sound. You’re a star.
One Word , IMPRESSIV
This man has patience :D
Great Work!!!
Your dog is so helpful!
Good job this is more realistic for my budget.
😂 Nice video, and amazing sense of humor 😊
But the wall panel is looking awesome 😊
good job! it actually did something; the fluttery echo is gone, the claps sounds more natural and nicer
Good choice not going with the walnut stain. It looks like you've got a mix of scandinavian and midcentury designs in your place - teak was a popular wood of choice in midcentury designs and could offer a really lovely warmth to contrast with the cool grays and neutrals in your space. I wouldn't recommend making something like this with genuine solid teak outright because it'd be prohibitively expensive but a danish teak style stain could be nice for future projects. Looking forward to seeing more.
Thanks! Will have a look at that ;)
I'm not so much into interior design and more do everything by intuition... but knowing the name of my intuition will be helpful for further design inspiration!
Holy f*ck. So much work. But the Video itself was really good, all the small nucks and grannys, the different angles and timelapses. Could not stop watching. Looking forward to seeing you both in real life again.
Higgens probably also misses the high life in the office :D
Nice workmanship. Clapping mid-frequency is 2500 Hz. Skyline 3D QD diffuses in X and Y dimensions so you are losing energy vertically. Your walls are exposed elsewhere so the diffuser does work but in relative terms, to the rest, you may not notice.
It is a very nice piece of work! Well done. I would hate to be your neighbor though with al that sawing...
You should meet that guy who was hammering out the tiles in his bathroom the past two days :D
I have a thick cotton wall carpet with a printed photo behind the listening position, it reduced the clap echo for 90%. So all good.
The diffuser looks awesome though
Nice job. Well done. Very attractivde. I'd suggest sorting the pieces into boxes for each size and using a pencil and ruler to transfer the pattern onto the backing then gluing the pieces onto its appropriate space on the backing. The backing by the away is called oriented strand board.
Great idea! Thanks!
7:41 Norman, I gotchu. Take an empty spray bottle, mix 1:1 water and house hold beach (8-6% sodium hypoclorite). And a drop of laundry detergent. Spray it on the black streaks on your balcony wall let it sit for 10-15 min and rinse it off. The streaks will disappear. If there not fully gone re apply or use less water in your mix. You're welcome - Roy.
You're doing a great job enjoying and creating neat things keep learning new things with every project. 👋 Great job Norm.
actually this coupled with some absorbers for the higher clap frequencies and some bass traps should make for great acoustics
and yeah you should put them at least near the height of your listening position and get the couch further from the wall , but i guess in the german highrise apartments space is tight. greetings from munich
You should make another video where you make acoustic panels.
Those will absolutely change the sound of the room and you could make them look quite beautiful while you're at it.
Would make for some good content as well.
Cheers.
Superb creation
Looks really good! You could also cut 1/2cm blocks if you have any left over & cover the screws - may look neater without visible screws :)
Nice video. Nice build.
Too funny, I can sit here without killing myself. This did absolutely nothing.
Love the video and seeing the whole process. Congrats on the build. thanks
this is the mitre saw, it mitres and saws... love it 👍
Great video. Will help me for sure with my build. Thank you.
Beautiful workmanship and pleasant aesthetic result. Congratulations, I'll start following you, thanks for sharing. SL
Great job, that was a lot of work and dust. I can't get around the fact that it doesn't work though. Better to have run a frequency sweep and check for differences. The hand clap sounds quite high in the frequency range. Absorption combined with this fantastic piece would help quite a bit. I also have read that there is a minimum distance from your seating position to follow. Complicated stuff, I know but when you get it right, magic happens. Any system will sounds it's best.
Thanks for the advice, but I always feel like a real world example is way more important then results on a data sheet... I mean what’s the point knowing there is a difference when you can’t notice it anyway :D
@@normanwink I didn't clarify it enough. I meant a frequency response sweep by ear, and record it like you did with the mic, now it's too late since you have it on the wall. No equipment involved. Anyway at least it looks great. Treatment has always worked for my set ups in Bars, Cafes etc. But it is complicated.
i love how you can instantly recognize a german accent even though its almost unnoticable
Very nice! Even if i think just one row looked way better
Danke für die Idee 🤘🏻
Lots of work, good stuff. Thank You.
Did you use a diffuser calculator? By the way, the reason that you do not notice a difference with clapping is that clapping is above 10kHz. Higher frequencies require thinner blocks.
Probably. I should add some regular absorbers :)
@@normanwink fabric wrapped Owens Corning 703 panels can look quite nice and are ridiculously effective at first reflection points
clapping isn’t above 10khz what are you talking about lol
@@gimmigimmigimmi what are YOU talking about. Why don't you just google before posting your dumb comment? A flat clap is 10Khz.
@@RamonSmits maybe with your tiny little hands, lol. Well now I need to go measure. I'd be willing to bet it's spread out considerably below and probably even a little above that point, otherwise it'd make a piss-poor impulse response source.
Assuming similar mic placement, I believe that I did notice a slight difference in echo or reverberation, but mostly when you were speaking. Honestly, I think the effect is helpful even if it is not as dramatic as assumed, much like the effect of having more soft home furnishings like cushions and drapery. The contribution one gets from projects like this is subtle but also significant. You may notice it more when playing music or having a dinner party, for example, but not so much when alone and performing single hand-claps.
Sweet, I'd love to make something like this! Thank you!
looks awesome and was worth it just for how good it looks,
few things from what ive read on this, it would help if it was the height of your head while seated and the height of the speakers (altho as you said in the video you could hit your head on it)
and de-fusion dosnt work well in rooms smaller than 4x4m and absorption is a better option in small room sizes.
my rooms about the same size and im tempted to make one just because i like the look haha
I loved that you were onnest
Looks really good! Btw which is that wrist watch your wearing ?
Good job, looks awesome,
I might just try this one out at my new place. Love the content you make.
you can definitely hear a difference when you talk on camera, before the diffusers your voice sounded more boomy and you could hear the reflections on the lower frequencies
Wow, it looks like NY city. Great job man!
Absolutely love these!
Well done!!!
The reverb at start vs end is very different IMHO. Looks great :-)
I was thinking of making one, but wow that was a lot of work!! Looks really great though.
I admire that this guy doesn't care about having to clean sawdust out of his sofa; damn it he's going to do some woodworking! Great project! Also, one thought is that you could subtract 5cm off of the length of all of those pieces and just remove the 5cm pieces altogether. This would reduce the weight, wood used, how far it projects off the wall... and also could allow for maybe something creative where there are no wood blocks at all, revealing whatever was done with the substrate beneath.
Great Video :)
this looks awesome!
Отлично получилось!
such a great video. definitely subscribing for more!
Thanks! Means a lot
Hi, cooles Projekt! Bin dabei, ebenfalls Skyline Diffusor zu bauen. Beim Schleifen hast du dir es etwas schwer gemacht. Ein Schleifklotz oder Schleifpapier auf dem Brett geklebt erleichtert das Schleifen deutlich. Den Laser habe ich ebenfalls und bin echt zufrieden. Den Arm am Stativ lege ich mir zu. Danke für den ungewollten Tipp. Der scheint sehr praktisch zu sein.
Das erleichtert die feinere Ausrichtung ;)
Hast du inzwischen den Diffusor fertig gemacht? Hab vor ein paar Wochen einen Standbandschleifer beim Lidl für 34€ geschossen, das wär damit ein Kinderspiel gewesen
Muy buen video te quedó bastante bien, se ve mucho trabajo pero igual es entretenido creó lo intentare.
Given the thickness of your collumns, you're not diffusing at high frequencies. Reason why there is no correction for hand claps. Diffusors on the ceiling would have helped too. Last but not least, rear diffusors should have been at ears height. Nice job anyway, very nice.
Thanks for the advice!
There are a lot of ways to improve the efficiency, a lot of commenters have been very helpful. Maybe I'll find the time to optimize it, but for now this is not my priority.
However, you guys are the best, thanks for your help!
maybe hollow blocks would help ? (but be hellish to make)
Would it be a good idea to make it out of foam or something similar that also absorbs the sound?
@@frankunderwood8357 no, diffusion is the exact opposite of goal of absorbsion. If you are absorbing the sound, how can you retime and reflect waves with the diffuser.
Cut the top face of the blocks at two different angles, for high frequency diffusion
Great work and cool video!
What ticks me off with building a diffuser like this is the weight. And the boring job with cutting all the pieces. But hats off for doing it they look really nice.
Btw I am curious of one thing and I hope you can answer, the speaker stand in the background looks like they are adjustable in height what speaker stand is that? :)
Also I am curious about the placement. Shouldn't they be in the same height as your head if they should work at the listening place to scatter the reflection direct behind your head?
It looks nice and will make an overall improvement to the acoustics in the room better.
First of all, thank you!
You are right: ideal placement of the diffusors would be at ear-level.
The adjustable speaker stands are a pair of K&M 26740.
I bought them for my studio monitors years ago... Setups evolve over time, so they somehow ended up in my living room carrying speakers which are almost cheaper than the stands themselves :D
@@normanwink Hehe well I guess it's great stands then. 😊
Will have a look at them. Seems that I need adjustable because it's hard to find "regular" stands that are 100cm or higher.
Thanks for the reply.👍
@@normanwink I gotta ask also, are they sturdy and not wiggely?
Sure I get that taller stand will be more wiggely than lower because of center of mass but like will they fall over from the slightest touch?
And I wanted to make acoustic foam.... I must make this!
I think that these things are not interchangeable...
Foam ist going to absorb the sound waves (and interesting fact: transform the kinetic energy into heat) while diffusors are going to... well, diffuse the sound waves so that your brain doesn't recognize it as sound (but the pressure waves still exist afaik)
For a good acoustic treatment, you will need both
I want a friend like you.
Diffusers disperse reflections, they don't diminish them. Your flutter echos are gone. It did exactly what it was supposed to do.
the sheet material is called oriented strand board.. OSB
love the accent, and the diffusor looks awesome!
Defusers are normally used to scatter standing bass frequencies. If you want to ubsorb hog freq sound, build some diy rockwool panels
nochmal angeguckt, immer noch für sehr sehr geil befunden! Übrigens die Platten bei 1:50 nennt man OSB Verlegeplatten^^
Nice but would it be better to make it with sharp ends?
That plain floor reflects a lot of sound, put a rug in there and you will notice the difference right away
Those are gonna be fun to dust.
Lol, the end with the soundtest is so funny. Too bad it didn't planned out the way you wanted it. But it looks nice!
That Modded Seiko though!
You sound like Liams character Caleb from Critical Roll. That's pretty cool.
Haha .. great video , love the dog...that looks awesome... But that isn't a sound dampening wall... It's a diffuser. It shoots the sound in different directions. Put 1 more panel behind the tv and sound dampening panels on your left and right... Then listen to some music....sorry I wrote this before reading the other comments.
When I first read the title of the video I thought you were making an actual city skyline out of wood and using it to dampen the sound (which would be cool but a lot of work), cool video still
das ist super!
I doubt that in our country South Africa , they can allow you to have those machinery in your balcony lol , I'm really impressed I wish we also has that much freedom here
I think putting up a curtain where to the entrance of your dining room? would help alot more with sound worth a shot
Great idea, but I think I wouldn't like the look 🤔
LOVE this!
i’m sure it provides some diffusion, but doesn’t help that it’s made from a reflective material. sound/noise works it many ways. great art none the less
Good job! Lots of work. Hope you didn't making the cutting on a Sunday. Your neighbors would love that😆. Thanks for the video.
Haha here in Germany within 5 minutes you'd probably have a lynch mob in front of your house if you do that on Sundays
Super cool looking. You could have hung that with a French cleat so you don't see any screws.
Tolles Projekt, hatte auch schon überlegt so etwas zu bauen, die Materialkosten waren mir allerdings zu hoch. Deswegen meine frage: wo hast du das Holz gekauft und was hat es gekostet? :)
Aktuell kannst du das bei den Holzpreisen vergessen, aber habe die ganzen Latten bei Hornbach gekauft
Habe damals 142,80€ für die Latten bezahlt und OSB kostet ja eh fast nichts
Top, danke!
We are creating various wood diffusers like this as a company. OSB is not the best option as the glue does not stick well onto these boards. Try plywood instead. Also the rounded edges are not too good if the acoustic is more important than decoration. Rounded corners makes holes which causes standing waves. Of course it's only important if you have a pro home studio, otherwise it does not matter too much.
The Problem for Sound is, you clap your Hands below the Diffuser, so it Reflexion hits the wall below the Diffusor.
