How I built an acoustic diffuser panel 

Sean Blank 🤙 thanks Sean everything I do comes out from my Saxophone, Happy you liked. 🙏🎷

Me too😎

Do you have pdf of the pattern?

Thx my friend, I like you comment. The birds visit’s me in all my video projects 🎶🎶

Thanks bro 🙏 I appreciate🎷

Thanks my 🎷🌈

Thanks my friend I really appreciate your comment. Stay tuned for more stuff 🎷✌️

@@ArikLivnat Already downloaded your pdf guide..thank you very much! One question. What is the distance from line to line?

@@brakeofficial6852 2.5- 3 cm

@@brakeofficial6852 Btw pleased join my channel it help me too👍

@@ArikLivnat RU-vid already did....😉

Thanks 🙏 yes he was one of my hero’s🎷 best!

Yep you’re right, &Tnx🎷

What exactly does that particular pattern do?

Diffusion and absorption

Thnx😊

😎🙏

God bless you 🌹🙏

Thanks Anthony, I’m happy it helps you. I’m here if you have any questions during your project 💪good luck 🎷🎷

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 ✌️

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

Hi sounds interesting hope you can upload something so I can see...

Thanks my friend 🙏 stay tuned for more..🙂

Thx man. If they work good 4 U

Thanks 🙏 my friend 🎷

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?

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 🍀

Exactly 👍 I made 4 of them and it’s doing a great job in the studio. Share yours too & Good luck 🎶

Tnx🎷

Tnx. yes indeed it is a very good solution for absorption and diffusion 🎷 go for it.👍

Thanks 🙏 my friend

Tnx bro🎷🎷 you do music?

🙏 you’re welcome. Stay tuned for more..

Tnx man 👨

Thanks 🙏🎷

TNX arik:)

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?

Tnx👍🏼

Thanks 🙏 my friend.. stay tuned for more 👍🏼

Tnx

Tnx👍🏼

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 🌼🎷

Tnx

Bob Smith thanks bob👍

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!

Tnx🤙

👍🏼

Thanks 🙏

Thanks

Tnx🌼🎷

Love to hear your music

Tnx 👍

Thanks Chad:)

Tnx👍🏼

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

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🎷

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.

Tnx👍🏼

🙏🎷

@@ArikLivnat thank you so very much for the quick response !good wishes frm Nepal ,sir .

@@studiobliss9796 My pleasurer my friend. I'll be happy if you will consider subscribe my channel if you aren't already. your support will help my make more tutorials. regards!:)

@@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)

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.

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 👍

No, Not random 👍

Yes you can find my plan in the description there’s a link👍

Tnx my friend 🙏🎷

@@ArikLivnat I have a great friend of mine that play sax in one of my songs of you want to hear it out its here on RU-vid Fidel Diaz - Reactor

Hi friend listened and liked (also subed to your channel) very good track. What are you playing there? The guitar? The sax sound interesting almost sound synthesized. Where are you from

@@ArikLivnat thnks (subed as well) Yes I'm playing guitar and bass. The sax 🎷 goes to one bus with a reverb and to a second bus with a stereo delay. I'm from Argentina but I live in Spain. You?

I like your playing very much, cool man. I’m Paris / Tel Aviv 🎷

Tnx

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👍

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/

Yes I made the slot with table saw 6mm wide.

Hi, yes I did use exact measurements. There is an accurate drawing and you can happily download it from my site: blog.ariklivnat.com/2020/09/24/how-i-built-an-acoustic-diffuser-panel/ You are also welcome to subscribe for more videos. Thanks🎷

@@ArikLivnat Thanks a lot. Is very helpful.

Good luck 👍

Yes you can if not to hang on the ceiling. (It can have belly)

Hi, it absorbs more low frequency, below 300Hz - but less high frequency - above 600Hz.

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.

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 🎷👍

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.

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👍

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 🎷

Hi the PDF is the right paperwork

@@ArikLivnat I can't agree with the measurement on the paper work of 7.5 cm... maybe it should be 3.75 cm

@aprop544 ok I’ll check it out again

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5wwkSoOaakU.html If you'll use both materials you will get a Significant result. 🎷

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

Hi, round 2.5cm bit

Thanks 🙏 In principle yes but this should be a triangle shaped construction. In the front you can make the stripes with the router

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. 🤙🎷

What about this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YlaBZQPSkK8.html

@@ArikLivnat Those are just standard absorption panels on wheels. A combo panel is a combination of a diffuser and an absorption panel.

@@ark9515 so the one you are watching is my tutorial: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GiM3KI-tkmM.html

Do you need the design sketch?

@@ArikLivnat Yes I need the sketch design on top of the absorber panel.

Pine wood and plywood

@@ArikLivnat thanks you 🙏

You are welcome 🎷

You are welcome 🎷

Thank you for your help. low cost people @@ArikLivnat

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.

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 !!!

Cada tira tiene una separación de 2.5 cm Cada espacio entre las tiras es de 2.5 cm a 3 cm.

Hi :) bit size 2.5 centimeters with 1/4 Router

Size or model?

@@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

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5wwkSoOaakU.html

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. 🎷

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?

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 🎷🎷🎷
