room measurement need help with treatment

[jwl]

Turn off smoothing in the program, this will give you a much more accurate picture of what's happening.

Your room is very close to a cube; therefore you will need even more bass trapping than most small rooms do. Put as many good bass traps into as many corners of the room as possible.

a more detailed picture. without smoothing.

i want to ask on a previous thread i asked about the right materials. wich density is better for absorbers and wich for bass traping

bass traps absorbers choosing the right materials

[Glenn Kuras]

I am not sure I would trust your test. There seems to be a lot of noise coming from somewhere from looking at the waterfall graph. Basically you going to have ringing but not like you are showing.

As far as set up, because you room is basically a cube get the speakers as close to wall, treat as many corners as possible with bass traps, panels in the early reflection points with thick absorption on the back wall.

any chance the noise is generated by my computer? because its a bit lousy

[PaulRain]

yes it could be easily the computer, the most noisy component is usually the PSU (Power Supply Unit), sometimes it really worth replacing it with a quiet one, no need to spend a lot.

You could build a muffler as well. My brother had this problem and he constructed a cup shaped flange made of absorption material and attached it to the back of the computer around the power supply fan.

in my opinion is cheaper to change the PSU

i have a good pc. i7 12gb of ram. but i have 7 coulers psu etc fans cpu fans etc + the video card coolers

Computers definitely can get noisy, which is likely where the noise is coming from (as it is low, but not way low in volume). Did you also have a ceiling fan on during the test?

As Glenn suggested, you will want to hit your first reflection points and corners with broadband traps. That really large null around 60-70 Hz could be due to your speaker position. Do you have a sketch of the room an your position and speaker position in it?

[djkaldor]

no celling fan. here is a scetch of the room

Try moving your speakers around in all directions. If the null gets deeper, changes frequency, or goes away you will at least know where it's coming from

[PaulRain]

first of all the monitor should not stay behind the screen, then I think you should try to move the monitors much closer to the front wall

its because of the rooms size i think. i will move the speakers as closer as possible to the wall and the basstraps since my room its not that big. do u think this will help? i will keep an equilateral triangle bettween the speakers and the sweet spot

i am also not sure if i understand how i can use these readings and how to take correct these readings.

for example. both speakers have to be placed to a mirrored symmetrical way to different directions and take measurements? also in all measurements the mic should be in the sweet spot?

yeah i will do move the monitors a bit more to the back and closer to the wall so i can make my the triangle a bit bigger for better stereo image.
about the screen i have seen many studios having the monitors behind the computer screen
