And yes, i mesure at 60dB, because i don't know it any better...my mistake. Is it really so bad? Beacuse i think i can't redo the mesurement in the near future...
The pannels are made out of 8cm Rockwool Sonorrock (40 kg/m³), packt in 7µm plastic sheet. The cover is made out of Molton.
And yes, basstrapping is my goal, but i want to make it right!
Hey, did someone had the time to take a look at those mesurements? It could really help if someone have a opinion...i'm a bit stuck here, don't really know where to start with the treatment. I would love to have some formulars to calculate some absorbers etc...
I took a look at the REW data, but I'm not exactly sure what I'm looking at! There are 20 different measurements in that file, with cryptic names that don't mean much. I assume that the refer to locations in the room where the measurement was taken, but but "bottom front edge L" doesn't tell me much about that....
Also, the levels are still too low: there seems to be a lot of noise in the measurements, so I'm not even sure if they are 100% valid. By increasing the level to around 80 dB, you will be greatly improving the signal-to-noise ratio, and removing doubt about the validity of the readings.
There's no calibration file in there, so I assume that you didn't calibrate REW either.
So what you should do is to first calibrate REW, both for the actual sound level in the room (using a hand held sound level meter), and also for your sound card, then take a new set of measurements with the mic located at the mix position, exactly 1.2 meters above the floor, on the room center line, and pointing upwards at 45°. Do one test with just the left speaker at a level of 80 dB, then do another test using just the right speaker, also at 80 dB, then one more test with both speakers on, and without changing any levels at all.
Post that new MDAT file, and I'll take another look at it.
