“There will be light”: unique DIY wooden sound diffuser wall art

Thank you for reading this post, don't forget to subscribe!

A. DIY wooden sound diffuser It is generally used for acoustic purposes. In my case, I did this purely for aesthetics. I've seen many versions of this idea, but decided to make it a cheerful, dynamic one. wall Art.

There is a lot of information online about what type of wood you need for an acoustic sound diffuser. Since we do it for art's sake, we don't need to detail all the technical specifications. Let's agree that softwoods and pines are good!

I used 2×2″ select pine; it is more expensive, but I thought it would look nicer since I cut the 1″ pieces at an angle.

To save on the cost of a DIY wooden sound diffuser, you can use the cheapest 2×2 inch one. It will require more sanding, but I'm sure it will also look very nice.

This project is simple to make and you can make it in a weekend. When I started cutting these pieces, the blade guard on my miter saw broke and I had to postpone the final result. Watch the video on YouTube to see what difficulties I encountered and how to replace the miter saw guard blade.

This took longer because I decided to hand paint all the pieces. More on this later.

You can make all kinds of designs with colors, but let me explain the “there will be light” thing.

My idea was to create an equation from darkness to sun/light. I don't think I've been successful since I finished it and my daughter looked at it, she saw…guess what?

A fish!

haha, this was unexpected. I thought about changing it, but I realized that art has to evoke an emotion in you. And if it's a fish for my daughter, let's be it!

The size of my DIY wooden sound diffuser wall art is 42×26″ (unframed), but the beauty of this project is that you can customize it to your liking, including the size, color, and shape of the pieces.


  • (5) – 2×2″x8' boards
  • (2) – 1×2″x8 boards (frame)
  • ¼” plywood sheet (size depends on your mural)
  • wood glue
  • acrylic paint


How do you make a sound-diffusing mural?

Step 1 – sand and cut the pieces.

This process will take some time, this is only 70 pieces

First you need to sand the boards. It is much easier to sand the longboard from individual pieces. Since I used select pine for this project, sanding was minimal.

You will need a miter saw to cut the pieces at an angle. I cut my pieces at a 22.5 degree angle. The long side is 1″ and the short side is ½”.

The smaller pieces were intentionally made to reduce some of the weight of the overall wall art. It could have been smaller as I don't care about the acoustic effect. But if you want to use us as a DIY sound diffuser, do your research on traveling sound and how long the tracks should be.

I'm sure there's a better way to cut on a table saw by creating a special jig. In my opinion, it was easier to cut with a miter saw.

I won't lie; This took some time. At one point I started cutting two boards at once and I wish I had done that from the beginning. This accelerated the work.

When the boards reached 4 inches, I left them behind rather than risk my fingers.

I made a mark on the miter saw so I didn't have to measure the angle every time. There was a lot of back and forth and it took me a few hours to cut it all out.

Step 2 – Finishing

I decided to have 17 rows and 27 columns. This probably shouldn't matter to you as you can make the size to suit your needs.

Once all 459 pieces were cut, I lightly sanded each piece.

Cut and sanded, ready to paint

Step 3 – dry fit

It looks amazing even when unpainted

Once all the pieces were ready I laid them out to see how they fit.

They looked so gorgeous I was wondering if I should just stain them instead of color painting them. But if you follow me on InstagramYou know I always choose the color.

Step 4 – cut the back.

Once you have lined up all the blocks on the ¼” sheet of plywood and decided on rows and columns, draw a line around the edge and cut the ¼” plywood to your desired size.

If you don't have a jigsaw or table saw at home, you can ask any home improvement store to cut it for you.

Step 5 – Paint (optional)

I wanted a dramatic effect, like a light coming out of the darkness.

My favorite acrylic paints

I chose as usual my favorite acrylic paints various blues, yellows, browns and oranges.

You can save time by spraying paint blocks. I wanted to see the grain as I did with the building blocks a while ago. I did a sort of paint wash using acrylic paint and drops of water. It's thin enough to show the veins but still has color.

Which route you decide to go is entirely up to you.

There are no real rules when it comes to painting pieces. Just a word of advice – It will probably take longer than you think. Perfect for a quiet night in on Netflix. It was a therapeutic experience for me, I just finished a season of a ridiculous television show and it took me a total of 5 hours to paint all the pieces.

Since it is always better to start with light colors, I started by painting yellows, but then I changed my strategy and continued with blues. Once it was dry I would lay it on the base and arrange it as I went. This way I could see if there were too many blocks of one color.

I love the colors! They are lively, dynamic and overall fascinating.

Step 6 – glue

Once you have adjusted the colors and are satisfied with this sound-diffusing wall art, you can proceed to glue the wooden blocks to the board.

You will need wood glue to glue the blocks to the board. Glue is easier to apply in rows or columns. I removed the last blank and slid all the blocks down.

Take a flat board and place it next to the edge; This way you make sure the edge of the mural is straight and even.

Apply some glue to the board and press the blocks down. Let it dry overnight.

Step 7 – make a frame.

You can choose to stay outside the frame, but I decided to make one. I made the same butterfly panel I made before. Measure the length of the mural and cut 1×2-inch pieces at a 45-degree angle on the miter saw.

To install it, I used a nailer and drove the brad nails directly through the blocks.

What are you thinking? I love the colors! Such a cheerful sound-dispersing wall art; It makes me smile every time I look at it.

I plan to keep it in my office to lighten the mood. And now I constantly see a fish there haha
