Looking good, mounting brackets are available too, different colours, different sizes, not too expensive (for my taste). The link above is only an example. Go to thomann.de and search for EQ Acoustics.
Yeah that is the kind of absorber i build myself. These are pretty basic and easy to build. My first attempt wasn't perfect but decent.
It cost me around 40€ to build myself a 120cmx60cm piece and that only because i used refined wood which was pretty expensive
I will send you guys a picture of the result. I pretty happy with it so far. This kind of absorber kill a lot of unwanted reflections and room noise.
- Never place your speakers near walls, always leave some space ... 50cm or more
- Check the internets for Basotect foam. It has very good sound absorbing while being super lightweight. Adhesive ones are very easy to attach to the ceiling. (100cm x 50cm x 10cm weighs 450g only as opposed to 1.5kg for PU foam)
- Only buy 10cm (4 inches) thick no matter which kind of foam material you end up buying.
- Don't try to soundPROOF your room, ever!!! Unless you have space and budget for a room-in-room build. The inside of a studio room must NEVER be totally dead. Put a nice thick carpet / rug on the floor and as a rough guidance, cover 50% of the walls and ceilings with sound treatment.
- Imagine your room walls and ceilings would be all mirrors. When you sit in the listening position, put foam in all places where you would see your speakers in the mirrors.
- Stay away from egg carton or pyramid shape foam!
The above will already make a HUGE improvement. If that's done you can still think about adding bass traps or other stuff.
1. I know that this is common practice but i have no option to keep 50cm distance. or else my desk would stand in the middle of the room
The foam behind my speaker helps avoiding early reflections. Hope this is enough.
2. Yes is stumbled upon the Basotect foam before. I had in mind to treat my bigger wall to a higher degree with this kind of foam.
Does ceiling treatment helps to avoing noise getting out of the room too ? or is it just to kill room reflections ?
3. 10cm ? Really ? I had more 4cm foam in mind. Would you say that below 10cm the effect wouldn't be enough to have any effect ?
4. Ok a room in a room scenario isn't necessary because i'm not the full volume amp guy. I use the kemper at maximum via my M-Audio M3-8 speaker
at like half volume. So not that loud and no real air movement. At least not what an amp would push. Do you think that my noise would be noticeable by my neighbors
even after a wall treatment ? Is foam itself that inefficient ?
5. I heard of that practice before. I'm not a friend of treating specific spots on the wall. I would imagine that the sound waves wouldn't directly reflect to
me anymore but indirectly after reflecting in multiple angles and hit me at some point so that i have still unwanted reverb. I don't want to sterilize my room acoustic.
But i'd rather treamt the whole area behind me as well as only just specific spots. Especially due to the fact that i want to prevent sound to travel through the walls.
6. Egg cartons aren't really on the list. But why no pyramid shapes ?
The wall behind my Desk is treated with these foam Panels

They do a really good job so far.
Bass traps would be one thing i can think off. But so far i have no issues with standing waves our bass collection.
I already analyzed my room acoustic via frequency generators. That way i can easily find room modes.
