Hi,
I recently moved to a new flat, and I've just got my studio properly setup in one of the rooms.
Congrats! I hope we get a lot of your beautiful music out of this room:)
Problem is, the room is rather horrible acoustically. As this is the room I've got to play with, I'm going to have to make the best of it acoustically.
So, my question is about DIY acoustic absorbers. I'm most likely looking to build absorbers both for mid/hi-end (I'm thinking the classical rock wool ones you place spaced out a bit form the walls) and for the lower end, but I am very much open for suggestions. Here's some specs of my setup:
- The room is roughly 3.60m wide, 3.40m long and 2.50m high. I think at least one wall is concrete.
As first step I would consider to mix facing the narrow side of the room
![]()
Plus always keep everything nice and symmetric.
Also I would recommend to measure the room to see what problems you're dealing with. http://www.roomeqwizard.com/ is available for Linux AFAIK.
- My mixing position/monitors is in the middle of the front wall. I sit about 1.20m out from the wall.
Have you heard about the 38% rule? If not read up on this http://realtraps.com/art_room-setup.htm, also covers early reflection points.
- My monitors are small, a set of Adam A3X (so 3" elements I guess). It basically gives very low bass response, so I can hear fairly OK down to about 80hz, rapidly declining down to 60hz where there's nothing left.
Less low energy buildup, but as you mentioned you won't know whats down there so I would recommend you to treat for lower frequencies in case you upgrade your speakers in the future.
- I am not terribly dependent on mixing at high volumes, if that matters.
It matters a bit as there is less energy to be absorbed, but again I would treat properly just in case you want to listen with higher SPL's, so it doesn't totally change the EQ of your mix (anyway it will change with sound pressure level because of equal loudness contour)
What I currently have is:
- Two large bookshelves along the wall right behind my mixing position acting as diffusors. These go almost all the way up to the ceiling, and has stuff unevenly stacked at different heights/positions in the bookshelf. They cover 1.60m in the middle of the back wall.
I've got good experience with bookshelves in homestudios, given they aren't to close behind the listening position.
- I also have a fairly large carpet on the floor in the middle of the room. It probably doesn't do that much, but maybe it does a little.
It does a little in preventing flutter echo of high frequencies.
My question then is; are there any effective ways of acoustically treating this room? Of course, given the topic of the e-mail, I'm very much willing to do my own DIY solutions, if that's a viable option. What I have been thinking is doing what I mention above; classical absorber "panels", and bass traps.
I would treat the corners and early reflection points first.
In a homestudio of a friend we filled the corners with rockwool made a wooden frame and covered them with fabric.
Early reflection points can be treated with 10-15cm thick "classical absorber panels".
For our live room we've done something else, we made wooden slat covered frames and filled the cavity with rockwool .
I like what it does to the room as it doesn't make it dead but tames the response quite nicely.
Thank you very much for any help and any replies!But, before I start anything, I'd very much like input from people who actually know what they're talking about (I'm looking at you on this list ;) ). So, does anyone have thoughts/suggestions for me? Any recommended way of doing this?
Best of luck!
Moshe
