If you have a room where you make videos, produce music or record any kind of sounds, surely you have an echo that bothers you and you want to eliminate it so that the quality of your work is the best, you can do this by placing acoustic panels on the walls and ceiling.
Acoustic panels are used to absorb sound, their main function is to reduce what we call reverberation (which is when sound bounces off multiple surfaces causing a slight dwell time once the original source has stopped emitting.) It also helps to eliminate echo.
Acoustic panels can be expensive, especially if we want our room to be 100% reverb free. That’s why I’m going to show you how to build your own panels and not leave your bank account at zero.
- Wooden strips (x2) 12cm x 1m*.
- Wooden strips (x2) 12cm x 66cm*.
- Rockwool (1) 98cm x 61cm x 10cm*.
- Long screws
- White glue
- Wood stapler
Measurements depend on two things:
1. The size of the panels you want to make
2. The size of the rockwool, the one I got is the size I placed, if you want to make them smaller you can cut it or if you want them bigger you can join them together.
To build the frame we form a rectangle with the 4 boards, it is important to measure the boards very well so that the rockwool fits perfectly in our frame. The short boards go inside the frame.
Then we proceed to drill two holes in the place where we are going to place the screws, we do this with the help of the drill to avoid breaking the wood when screwing.
After we have drilled the 4 holes, we place the white glue, join the boards and proceed to screw them together. After having placed the 4 screws we do the same process on the other side.
When the frame is ready, we place it on the fabric and stretch it very well. Then we gently place the rockwool inside the frame (I recommend you to use gloves and a mask because of the particles that the material gives off).
The next step is to place a rectangle of cardboard covering the whole frame, this will be the back of the panel, so it doesn’t matter if you use an ugly cardboard box. The cardboard is attached to the frame with the stapler.
Stretch the fabric very well inwards so that there are no wrinkles and fix it with the stapler to the edge of the frame, also going through the cardboard. I recommend that you make some folds in the corners so that the panels show very well.
It is advisable to place 1/3 of panels on the walls and ceiling to achieve an optimal result; it also helps a lot to place a carpet on the floor to prevent the sound from bouncing and echoing.
