hello!
well, first cover your wooden floor with a carpet, to avoid too much reflections from your floor (you would like your room to be
with the flatest frequency response as possible...) there are a few calculations and
formulas, that you messure the diamater of your room + you take in acount the meterial
its made out of, and then know wich frequencies will be boosted and cut within your room (pressure nodes and anti nodes...)
(if you want i can post later the formulas and basic principals) by that you can know
wich kind of absorber, difuser or other mean
to get over it...if its just spunge your using, tell a freind to sit in the place were
you sit in the studio, take a mirror, and walk along the wall, in the spot were you see
your friends ears, locate the spunge (do so olso on the other side). thats in order to avoid getting the early reflectoins direcltly
from your room (or at least weaken them) to
your ears...
hope i helped.

The absorber is Bo50, i have around 10 plates 120x80cm each(wave). I've visited on SAE.d website and have found there quite great explaination for recording studio. My question is what the basic things i should do.
thanks

H20,

The basics:

As Orik said, have your friend run a mirror along the walls/ceiling while you sit in front of the computer. Anywhere that you can see the speakers in the mirror will be a source of interferring reflections of noise. Cover these spots on the wall.

You should also fill the corners of the room with a heavy/dense material (rolled up sleeping bags, bags of clothes, foam, rolled up carpet, etc) from floor to ceiling. These 'bass traps' will cancel the big bass standing waves that corners can generate.

Those are the basics. If you want to be really hardcore about it you can buy some rolls of R19 insulation, cut them into 3 foot strips, and fill trashbags with these pieces of insulation. Then you staple them to the walls/ceiling until everything is covered. It looks ugly, but a little bit of thin carpet over top of them looks nice, and they'll kill just about every reflection as well as any outside noise.

No different than the walls - hard and flat surfaces reflect sound vibrations, so cover them if you can.

I never saw studio covered 100% with sponge. Usually it goes with wood as reflectors and sponge as absorbers.
Stas visit here http://www.saecollege.de, all answers i found there.

well...about the wood its usualy not a reflector, because you dont want to get reflections, in order to hear the direct
sound, so the wood is usualy diffusers, meaning they spread speciefic freqs, in order
to atenuate them, its used for frequencies wich absorbers would not absorb, but reflect.

about the 100% carpet...you wouldnt want your
room to be too dead, its realy anoying and gives a very uncomfertable fealing.
it dependes on the thiknes of the carpet,
metereal,etc..., the floor you actualy would want to cover with something...it all dependes on the dimentions, shape, and the
meterials of the room...
