Hi, I have to finish a mix in two days and I'm stuck at home. I can either mix in: - A small untreated bedroom (10' x 12' with 9' ceilings) - Sheetrock walls, ceramic tile floor.
- An open living room (19' x 24' x 12' ceilings) - Sheetrock walls, ceramic tile floor, one of the walls is insulated with rockwool.
Absolutely no treatment, but I have 2 queen size mattresses and 3 twin mattresses that I've placed in the small room in the corners and sides and the room sounds relatively good. I measured the small room with Soundworks and it doesn't look that horrible (see attached pic).
But when I go to the large untreated living room it seems like I gain an extra octave in the bass, even though it's completely untreated. However, the reverberation of a clap is of about 1 second (!). My gut feeling is that the large room helps me hear much more detail, but can I damp the reverberation with the 5 mattresses? How would I place them? In the middle of the room, behind me?
Or should I just stay in the small room? I've added the RealTraps mode calculator results, but I don't know how to interpret them.
Thanks!!

If you can't really treat neither of them(matress wont do it) just mix a version of a song in the smaller room, as good as you can. Then do another version in the bigger room, again as good as you can as it would be the version that's going to be released, and see which one is better. This is your best bet to achieve the best results in two days, given what you have.

Mattresses are not recommended for acoustic treatment but anything in the room will do something. When is comes to treating flutter echo, even regular furniture and stuff on the walls like framed pictures etc. can help minimize it... an empty room is the worst!
Try to localize what parallel surfaces are reflecting and put something (you have mattresses so try one of them) on one of the opposing reflecting areas. Mattresses are not very absorptive so if you stand them at a slight angle, you might be able to re-direct the reflection in a non-parallel direction; try to direct it away from your listening area. You might also need to get it higher up near the ceiling so consider propping is up on a couple of chairs?
This is absolutely a "cheap and dirty" way to treat a room quickly with what you have on hand. Pasim is correct about mattresses acoustic effectiveness, especially when compared with actual absorbers but I'm trying to give you help with what you've got.

Bigger is better. Further boundaries, weaker reflections and lower fundamental mode which means lower Schroeder Frequency which means less resonant bandwidth. One downside to that room is that 12' and 24' dimensions reinforcing a single octave of frequencies. Either way, the bigger room will be better regardless.

Yeah, I agree with Hexspa on all counts (wish I would have said that:)

Yeah, I agree with Hexspa on all counts (wish I would have said that:) You guys said everything else so I had to come up with something! To clarify, the two boundaries will reinforce a single note within each octave. Let's say the frequency wavelength/room dimension relationship reinforces 70Hz. Then a boundary half as long will reinforce 140Hz. What's more, that longer boundary will also reinforce 140Hz. What's worse, you won't have 'modal support' in the interim ranges. 'One Note Bass' is the result. |

But since both rooms basically untreated, both will have problems, and its a matter of luck in which one you can achieve better mix. Depends on the key of the song, what style of music etc etc..
