Nice job! Very pleasant to watch too with all the saxophone and the occasional birds calling out. 😊
Thx my friend, I like you comment. The birds visit’s me in all my video projects 🎶🎶
came to learn about acoustic diffusion. I stayed for the sax... well done.
Sean Blank 🤙 thanks Sean everything I do comes out from my Saxophone, Happy you liked. 🙏🎷
Me too😎
Do you have pdf of the pattern?
I've been looking for a DIY combo panel solution. And this is perfect for my needs. Excellent work on the panel.
And really appreciate you making the plans available.
Thanks Anthony, I’m happy it helps you. I’m here if you have any questions during your project 💪good luck 🎷🎷
Started watching to learn about DIY panel and then stayed for the sax.. what a treat sir... thank you for both.. 👏👏
Thanks my friend I really appreciate your comment. Stay tuned for more stuff 🎷✌️
One of the Best Ideas of SoundProofing is "SoundProof Curtains" That Stops Outside Noise by 80% (25 Db) Tested. Check Here: livesoundproof.com/best-soundproof-curtains/
They look good! I was thinking in make them curve, I’ve been reading a bit the difference between absorber panels and diffuser panels.
I came to the conclusion that both improve the acoustic in a room.
Your design is cool though, thank you for the idea.
Thanks 🙏 yes they’re doing a great job in the studio. If you’ll do the curve design, I’ll be very happy to see your result... that sounds interesting. Keep me posted 🎷 bye ✌️
I feel so calm and relaxed! AMazing work
God bless you 🌹🙏
Beautiful, also the music. Thank you.
Thanks 🙏 my friend 🎷
Very nice build and excellent sound!
Thanks my friend 🙏 stay tuned for more..🙂
You are the man... After a looot of youtube videos, this is a serious one! Also the sax play is incredible !!!!
Thanks my friend I appreciate 🎷🙏

Don't bother scrolling to the comments it's just people saying "it's not that, it's this, blah blah blah". Looks good and sounds good. Great playing btw.
Thanks bro 🙏 I appreciate🎷
Very talented! Very clean job! Congrats
Thanks 🙏 my friend
I like your adventurous playing. Kind of reminded me of Brecker. And oh, nice panel too ;)
Thanks 🙏 yes he was one of my hero’s🎷
best!
Love ❤️ the music as well ✌️
❤️🎷
Nice build. I'm trying to come up with a sound diffusion and absoption system for my personal studio. I can't decide on what I want to do, but this helps with my limited budget.
Tnx. yes indeed it is a very good solution for absorption and diffusion 🎷 go for it.👍
Great playing!
Thanks 🙏🎷
great video man ,plus great music uffff
Tnx🎷
Very nice... I’m also a (sort) woodworker and sound designer, and want to combine my skills to make my mix room look great and improve the acoustics. Thanks for posting!
Hi thank you too. I really like the sound of this diffuser. I have built 4 of these and they give an interesting sound. You will of course also need additional acoustic panels (depending on room size). Attach a video that will also show your work if there is one online. I would love to keep sharing ideas .. Take care! Keep Safe, Arik.
Did you tried to do your own?
Good job! Very talented! Perfect!
Tnx🙏🎶
Nice work !
Hiya, Thank you for sharing this amazing video.
Could you please tell me which Router is this and what bit did you use to cut into the plywood like that?
Many Thanks
Cool vid man, really digg the design.
Tnx bro🎷🎷 you do music?
This would act as a 1 dimensional scatter plate creating diffusion and absorption similar to what I see a number of vendors out there offering. Well done.
Yep you’re right, &Tnx🎷
What exactly does that particular pattern do?
Diffusion and absorption
Really cool video! Keep up the good work. Ive never seen anything like this
Tnx man 👨
Nice. Thanks for posting.
Tnx👍
Wanted to say that I love your yard :)
Thnx😊
That's an amazing job .. I wish you were talking in the video and explaining it. I bought the tools to try to build it I didn't have a router lol. Btw fellow sax player here your tone is amazing
Thanks my friend. I admit that talks about the process would have helped but as a musician I prefer playing..🎷😄 I’m trying to combine both arts… go get the router and start your project💪 good luck 🍀
Excelente!

great old school jazz horn, Arik! nice build, too :-)
Thanks my friend 🙏 glad you liked
@@ArikLivnat Nice whole tone melodies blended in with the modal stuff. And cool looking panels, too.
As i'm thinking of moving my recording setup into a big room at home which has random stone walls ("pierre apperent" as it is called here in France) the room, even with a ceramic tiled floor and basically rectangular shape, sounds pretty good. Not sure, but it seems like the rough surfaces of the wall help break up a bit of the parallel room modes already, but several of these designs on stands behind where i will be monitoring/mixing from, would be perfect.
And, the perfect project for my new router!
Thanks! Will definitely building several of these!
PS, interested how the calculations were done for the slot lengths as per this design. Did you calculate them? Or was it a tested design already?
Oh yes, liked and subbed too.
Thank you man, you have a good ear :) Sounds interesting your space, Do you live in Paris? J'adore Paris ... I would love if you share a video of what you'll create I will happy see what you did🎷🎷
@@ArikLivnat hi! No, I’m in the Charente in the south west of France. Moved here from England nearly 5 years ago from London
Thanks for the video! Do you know which frequencies this design absorbs/diffuses and reflects?
Hi replied also on the comment in my blog.
Did some tests it absorbs more low frequency - below 300Hz - but less high frequency - above 600Hz.
Bravissimo!
Thanks 🙏 my friend.. stay tuned for more 👍🏼
This is great 👌👌
Tnx👍🏼
Awesome vid!!
Tnx👍🏼
Rockwall behind works as absorber and wood surface in front works as diffuser and reflection, so it's 2 things in one panel. I am thinking to do the same. Thanks for your video.
Exactly 👍 I made 4 of them and it’s doing a great job in the studio. Share yours too & Good luck 🎶
Very nice!
Thanks Chad:)
That looks SIIIIIIIIICK! great job pal👌🏻
Thanks Lee:)😀
@@ArikLivnat do you sell them or just make them for personal use Arik?
More for personal use.. but if you need help in making them I can give you some good tips 😊
It’s just your impressive array of tools I don’t have the rest I could follow along with it’s ok if you ever do start selling them put me at the front of your list please haha
You are in my list 😎 where are you from?
Not sure what I enjoyed more, your film making skills, your building skills, your editing skills or your playing! Wonderful job! I have a question, when making the diffuser slots, does the size of the holes matter or can you use any random pattern?
Glad you liked the whole package :) As for the slots it definitely matters. I looked for absorption and diffusion and found the right measurements after all sorts of tests. You can download my drawing for free. Link in the info of the video. Thanks🎷🎷
Arik Livnat awesome, thank you. I have already built some absorption panels but as much as the diffusers help with the sound, I also like the look!
@@ArikLivnat Where did you find the measurements? A website? A app? I'm sure it depends on your room correct? Awesome work
I did some research.. as I mentioned you can download the plan💪 Tnx 🌼🎷
thanks a lot for the measurements
🙏 you’re welcome. Stay tuned for more..
Looks beautiful! How did you determine the length and width of the slots?
Thanks 😊 I looked at panels in studios that I played in.. then started to do my own calculations based on others. The sound in the studio came perfect. You can download my design in the blog look in the info🎷

TNX arik:)
I originally tried this method and then realized a totally easier way. Build a jig using a table saw only. Square ends simply place jig over each panel and route out.
Hi sounds interesting hope you can upload something so I can see...
very nice
Tnx
Wow!!
Tnx🌼🎷
Love to hear your music
Btw..Love the sax sound
Tnx
Hi, what a wonderful job you did here. I have a question, could this be used as a bass trap for the corner of the room? They are pretty expensive and this seems like a cheap good looking idea.
Thanks 🙏 In principle yes but this should be a triangle shaped construction. In the front you can make the stripes with the router
Thank you
🙏🎷
nice!
Tnx
do u think this is as good as RGB diffuser,,, if this thing absorp and diffusse in one package do u think its a good idea if i put this kind of acoustic pannel only in all my recording room studio?
Hi:) it does a big effect but I did use some classic acoustic panels too... so i'm using both. Please check the video about the acoustic panels: ua-cam.com/video/5wwkSoOaakU/v-deo.html
If you'll use both materials you will get a Significant result. 🎷
Arik, thank you. AMAZING! I have a couple questions. First what ratio of these combination panels to two basic absorption panels would you use? Second I'm concerned about the safety of mineral wool and am considering densely packed bulk cotton instead. (Hopefully it will offer appropriate absorption.). Are you concerned at all with the safety of mineral wool?
Hi there👍 thanks 🙏 in my blog you can find all dimensions sketch this is the link: blog.ariklivnat.com/2020/09/24/how-i-built-an-acoustic-diffuser-panel/
Concerning safety materials I used Non-flammable rock wool, but I’m sure there are other materials…
Let me know if the sketch ✍️ satisfy you👍
They look nice, did you pick the slot dimensions randomly? If not, care to share the scientific process to calculate them?
Hi, did my own tests and find it perfect to my room. 🎷
Here is the dimensions chart, You are welcome to use my design blog.ariklivnat.com/

According to the averages of your PDF, the remainders at the continuous ends that are 3.75 and not 7.5 are 30 spaces of 3cm and 21 spaces of 2.5, this would give 112.5 cm
sound wise, is there a rule to follow in order to decide how many openings and how short or long, or even the shape of the openings in the panels?
Hi:) yes there are rules... I found them from recording sessions, then I learned a bit of the field... There is a link in the body of the video to the exact plan I made for this panel. Feel free to download. Thanks
It seems the link just goes to your site and not the plans anymore. Any chance you can update the link?
I updated 👍
Wonderful design !cud u plz provide the list of measurements of the slots for smaller ones(panels)?prime numbers I guess ?thank you.

@@ArikLivnat I just subscribed..btw,slot length sequences for smaller size panels than the one u made in the video ?wud be helpful.or wht r the other prime sequences?
Glad you subscribed 👍 As for the thickness size of the slots can be 2 cm instead of 2.5 cm. The ratio between the slots should remain as in the drawing, but the lengths can be shortened. What is important is to leave 5 cm gap to the frame (in the long slots)
Hey what's the name of the machine you used to actually cut out the wood? What was the size of the bit you used?
Hi :) you mean the wood router machine.
You can free download my detailed plan in my blog. See the link in the description of the video👍
Did you use a diffuser calculator to work out the area of the slots?
Hi no. Not a calculator. Lots of tests while working… and then I tried them in recording rooms in different sessions. If you are interested you can download my pdf dimensions drawing on my site. The address in the info of the video. 🤙🎷
How did u get those side frames woods? Did it came like this (with slots) or u made by yourself ? 2:56
Yes I made the slot with table saw 6mm wide.
Can you change the width by a 1/3 or half and these diffuser is still effective? cheers in advance
Yes you may, but you’ll have to calculate less stripes or larger board🎷
@@ArikLivnat well I hope you explain how to do that in an upcoming video lol
cheers for your response.
how do you know the arrangement of holes and their lengths?
Nice diffuser! Good Job man! Help!
Thank you
Hi Antonio, thanks for comment. I am a musician but not a professional carpenter. But as a jazz musician I like to improvise and and the same with woodworking. I recorded in a lot of studios and saw a lot of diffusers. I ended up doing my own blend from all the things I saw and loved. If you want, I can give you exact dimensions of the diffuser beyond what I showed in the video. TNX
@@ArikLivnat yea! Please. Thank you man 👏
@@ArikLivnat I would love to see the designs. Great job on the work and video and of course the sweet sax performances.
Rob Kuhlman thanks Rob for your comment. I will try to add link to my Exact dimensions very soon💪 thanks
Daniel Joveski I will add a link to the dimensions very soon.. Tnx 🎷
Is there mathematical principle on how do you calculate holes, or is that irrelevant?
Hi Nick, I made holes 2.5 cm thick and 2.5 cm spaces. I did some tests and it sounded the best. 💪🎷 thanks for your comment
@@ArikLivnat Thank you for the response 💪🏼
Nick Chase 🎷👍
Cool beans

Thanks 🙏
What math did you use to figure the panel dimension and slots the you routers?
It's not math, it's more listening and looking thoroughly at panels in the studios I've recorded in. I tried all kinds and found the right dimensions and sound for my studio.
איזה יופי
Gabriel Baharlia היי גבי תודה כיף לשמוע❤️
in what frequency range does it work thanks
Hi, it absorbs more low frequency, below 300Hz - but less high frequency - above 600Hz.
How did you calculated holes (it depend of frequency)?
Yes you can find my plan in the description there’s a link👍
Hey have a question and I live in the United States what size of router bit in inches for the size of bit that you have
Hi it’s 2.5 cm= 0.984 inches

Which bit and size u used to router ?
Hi :) bit size 2.5 centimeters with 1/4 Router
What router bit was used to cut?
Hi, round 2.5cm bit
How did you determine the hole size and locations?
Hi 🎷 I Checked a lot of panels in the market and studio recordings.. and resigned my own blend. There is a link in the description for my design.
That is an acoustic resonator! It works like an absorber, not a diffuser. Very clean work btw!
Ok.. anyway thanks my friend 🎷
no you are wrong .it does absorb but the plate on top scatters/diffuses a bit of the higher frequencies
Exactly!
Are those random slots?
No, Not random 👍

I will appreciate if you will give a credit and a link to my UA-cam channel. *Please support by subscribing my channel.* Good Luck! *blog.ariklivnat.com/*
Lovely job and looks great. But it's not a diffuser - it's a differential absorber.
smokinvalves Thanks for the comment. Okay I accept the definition. Anyway, the panel not only absorbs the sound very specially it diffuse it a bit too🎷. Thanks
Will thinner plywpod can work
Yes you can if not to hang on the ceiling. (It can have belly)
Can you make a tutorial on how to make "combo panels"?
What about this video: ua-cam.com/video/YlaBZQPSkK8/v-deo.html
@@ArikLivnat Those are just standard absorption panels on wheels. A combo panel is a combination of a diffuser and an absorption panel.

Do you need the design sketch?
@@ArikLivnat Yes I need the sketch design on top of the absorber panel.
This seems to be a version of what is called "binary amplitude diffuser". If so, slot lengths must follow some mathematical pattern. Where did you get those numbers from? Any formula?
Murat Ozer
Hi, My knowledge in the field is from hours of recordings in studios. After spending hours in studios I gathered information on different types of panels that I liked and this is one of them. The binary diffuser seems very difficult to calculate... Anyway there is a chart dimensions of my panel in the link attached in the info. You can also watch more panels I have designed and built, the results are very good to the ear

no one :
music producers : why does people playing instruments have better equipment than me.
How did you find the dimension of the design??? Is there any formula!!! Plz. Help 🙏, I want to build designer acoustic panel using rockwool..
I did my research 🧐
You can download my scratches design- blog.ariklivnat.com/2020/09/24/how-i-built-an-acoustic-diffuser-panel/
@@ArikLivnat I am thinking to take inspiration from GIK acoustic designs but don't know exact measurements but they use 6.23mm board on front.
@@theshopper6902 are amazing, but I don’t know their dimensions .. anyhow I used 6mm front board
@@ArikLivnat I am just looking to stop echo or reverb in my 300sq foot empty Hall, so that I can speak normal directly to shotgun mic. Without recording echo!! I THINK having simple design will do the trick.. Or I will leave more holes for absorption than diffusion at front as that is only for me a aesthetic purpose.
So maybe you need just an acoustic panel
Check this out: ua-cam.com/video/5wwkSoOaakU/v-deo.html
Is the length of the holes random ??
No it’s not random. Here is my plan in my blog. blog.ariklivnat.com/2020/09/24/how-i-built-an-acoustic-diffuser-panel/
@@ArikLivnat thank you !!!
What does it actually do to the sound ? Most comments say it doesn’t diffuse the sound, so I’m interested to your ear what it does ?
I like you are a musician 1st and would trust your opinion over some of the “experts” who have no idea how actual instruments sound
I’m going to try and build one and retrofit onto my home-made absorber in my home cinema.
Hi Michael:) bottom line it sounds great! I was looking for an element that would absorb sound but not fully. You're right I'm a musician and after many hours of recording in studios, I found this panel best suited for my space, so I started to design my own. It's true what they wrote in the comments, it's not a full diffuser .. but it both absorbs and remains a gentle diffusion because of the slots in the plywood. I think sound is first and foremost a matter of taste. To me this panel does a great job and I built 4 of these. You can download my dimensions drawing in the link in the info. If you have more Good luck with your project too. 🎷
What wood do you use?
Pine wood and plywood

@@ArikLivnat model
@@studiooversound6597 It's a 1/4 inch router, I don't know which model, but there is a sketch that shows all the info. Link in the info of the video
It looks very good but it is more like an absorber, not a diffuser? Diffusers scatter the sound using a lot of different angles and shapes, but this only has one flat surface with an absorber behind it... If you really need a diffuser, this is not what you should build. Very good design and woodworking though!
Thanks for the feedback Harald! The truth is that it is not completely absorbing... It absorbs and resonates. I also built panels that are more absorbent and I will put a separate video about it. I recorded the saxophone at the end to hear the echo from the diffuser wood- It absorbs and diffuses gently at the same time. Anyway thanks for the diagnosis :)🎷🎷
Was my thinking too but if it makes a difference then it's great anyway. But it looks really nice! Will probably do something similar myself.
Let's lower muddy freq through, and scatters mid and high so they stay pleasant ✊🏿 fella knows his stuff
I think it does not absorb very much (at least the low freq). Much too much holes for that surface (ratio should be 3-4%). Or am I wrong?
It absorb more than it defuse. And it is doing a Quite interesting result in the room.. very good to my studio
Use your own design.
Yes mine. Tnx
Hey Arnold music lol
Who’s Arnold?
@@ArikLivnat hey arnold is nickelodeon's cartoon. I watched it a lot when I was a kid.
Ok Tnx .. but how its connected to the video?
Those types of diffusors are only a small bandwidth of high frequencies. they do not have the range that a Quadratic Diffusor does. The problems with Quadratic is you need distance between the diffusor and the listening position, and they are costly, especially when you consider that you're going to need at least 70% surface coverage to get a proper diffused sound field, so you're entire rear wall would almost have to be covered with Quadratic Diffusors.
But those BAD panels you're making only diffuse higher frequencies. Quadratic Diffusors, the higher the Prime Sequence and the deeper the cabinet can go down into the mid range frequencies down to 200hz for a Prime 23, but there are expensive.
There's a company that sells Build plans to make Quadratics and other treatment for low frequencies called Acoustic Fields, so if you're a DIYer, I'd check them out, they have the best low frequency absorption technology using Activated Carbon and their unique Diaphragmatic absorption cabinet design.
Made 4 of them, working great in our studio, musicians adore the result. It absorbs more low frequency, below 300Hz - but less high frequency - above 600Hz.
We tried some of the other you mentioned, we didn’t like.
Sorry good luck👍
@@ArikLivnat What did you try that you did't like?
@@ArikLivnat You made 4 of what? What products did you try that you didn't like? Your comment was very vague and cryptic.
4 of what I built in the video. We tried a a professional quadratics panels manufacturing… and we didn’t like the results at all, so I decided to build them. So much better…
best🎶👍
@@ArikLivnat First off, you don't sound like you have a strategy for treating the room.
You first have to figure out what the problem are and then pick the right treatment, and place it within the room to fix those problems.
Just buying treatment and sticking it in the room is a time/money waster because you don't have any strategy.
Quadratics work great, but you need to have the rest of the rooms' problems fixed first AND you need to have make sure you have the right Prime Sequence for your room.
Not all rooms have enough distance and if you don't treat the other problems in the room, then Quadratic won't work.
For room treatment, the biggest problems are low frequency Axial mode problems. Those are the biggest problem with most small rooms and they require a lot of space, and are costly as they tend to be at least 12 in deep cabinets that can also get as much as 16inch deep and you need to have a fair amount of them starting with the front of the room where the source (speakers) are located working your way to the back of the room.
BAD panels are NOT going to fix low frequency problems that are in that 30hz to 50hz range. They are simply not the right type of treatment for that. BAD panels are also not wide range diffusors like a Quadratic.
Yes, they might absorb down to maybe 100hz, but depending on the material and thickness, they can only do so much in terms of amount of absorption. As far as diffusion, they aren't going to diffuse a wide frequency range, they only diffuse a small range in the upper frequencies and that's all they really do in terms of diffusion.
But the first thing first, what are you using the room for and what are the dimensions so you can figure out the low frequency problems first.
I seems as though you are only treating reflections and no pressure based problems in the room. Also, to really treat a problem, you need at least 50% to 70% surface coverage.
For safety reasons you shouldn't use gloves with rotating tools. Instead of a scratch on your skin the glove will get cought and pulled in. Nice video nonetheless.
Thanks 🙏 yes after this video I took off the gloves
this is not a diffuser it is an absorber
It absorbs and diffuses at the same time
Love the work, great design and workmanship, great video.
However if you continue to label this as a diffuser, you are misleading people with an incorrect tutorial for what they actually need. You are aware of this, and don't seem to to care enough to change the 1 word in your title from diffuser to absorber. Quite sad.
I really do not agree with you. This is not normal absorption. The stripes create a diffusion. I tested it during recordings in different sessions on different instruments and soundmen who took part in the test
