My room in new flat has got pretty bad acoustic, huge windows height ceilings and brick walls. How to resolve it? This one is coming behind the speaker.
In the beginning I have had few major ingredients:
– loads of wood board 2 x 12 x 240 cm
– white bed sheets
– acoustic Rockwool 60gsm 60x120cm 10cm thickness
– wood screws
– strong rope to hang them
Data sheet for mineral wool

Sound absorption panels trap acoustical energy (sound) and prevent it from reflecting off of the surfaces they cover. The panels are used to eliminate echoes and reflections that muddle or color amplified music and speech. These wall panels will also reduce reverberation levels in a room, which can sometimes provide ambient noise reduction.
– Drill with drills and counter sink tool
– Sand paper
– Wood screws with screw driver, no glue is used in this project.
– Staple gun
Idea behind is to make nice looking cheap acoustic panel. Have I succeed? Take a look:
In the beginning, there was a horde of wooden pine boards. Light and nice looking from BnQ (UK DIY store).
Hand sawing in my spare room. Don’t mind dirty cloth for washing :)
Hand sawing and sanding. All together 11 panels + 1 Accoustic picture (which was made previously) = 44 pieces of bords were needed. Quite hustle make it all by hand. Mineral panel is 60×120 so I cut wood 59.5 x 122.5 to achieve tight fit.
Then drill holes and counter sink them. Counter sinking is quite good trick I learned, wood is not cracking when wood screws are coming in. I was feeling like in some kind of Ford factory, instead of doing one panel at time, I’ve made it step by step.
First frame is almost completed. Too many screws must be screwed so later I used hand drill instead. It went quite fast.
11 wood frames are ready to get white sheet cover. They are actually right angled and all in same dimensions. I’m satisfied with my work so far.
Cut half sheet (or tear) with scissors and spread it on floor.
Attach one side with staples, then opposite one. Make sure all is stretched at all time.
Same one, first slightly stretch and attach one side and then properly stretch the other one.
Now all sides are attached, cut the excess with with scissors.
Fold nicely corners. I have fold them on top side, so they’re not seen. This what I call perfectionism. No glue was used. Just staples, no bullshit :)
Evenly tack it in with piece of wood. Mineral wool is a bitch and tiny pieces of glass punish your pride if you don’t wear gloves. Some even recommend disposable apron and respirator. Mineral panel is 60×120 so I cut wood 59.5 x 122.5 to achieve tight fit.
Panels are queuing to be hang on the wall. Project get on pretty well and they all look and measure same.
I stack them behind speakers and partially in the corner. 3D acoustic diffuser is coming behind hifi rack (when I have time to do it)
This one is going behind Vintage Pioneer speaker. Because speaker is very close to the wall, there are some nasty low frequencies cumulation behind.
Two panels are also standing, so I can change position in the room and adjust acoustic.
Thanks for reading.
