how much will it change my sound?
right now i work in a room with out acoustics at all exept a thick carrpet on the floor.
will it change my mix and cleartiy of the sound that much.
i ask this dumb question cause the day before i went to a studio with the same monitores and the sound that came from his vsti s r alot sharper then in my studio n thats befoe eq n mix im talking about a simple preset could it be that my acoustics n audiophile sound card arent enough for this level of sound(pro sound)? |

Offcourse it will be changed.
Afterall the sound that you hear is a sum of sounds you get directly from the monitors plus the reflections you get from the walls and furniture.

it is posible that u'r room is already well acoustic area
well killing the reflections (drying the room) is prety easy but.......
u can easely dry it too much
it will cause not very comfort surrounding for work
too dry rooms r kinda 'Clinic" sound
feeling like u in small chamber deep deep underground
acoustic enviorment measured by RT60 i think ( time that make an hi volume impulse go down by 60 db) time that takes to all reflections (reverb) to disapear
i can give u examples for RT's
RT of opera halls is about 3-5 seconds
RT of acoustic jam studio should go aroound 0.3-0.5 sec i think
RT of mic room should be arround 0 (totaly dry)
again trust u'r eyers 
i suggest u to make a copy cd of u'r music and play it in u'r friend studio and some other studios with same speakers
if u hear u'r mix perfectly clear and familiar to u'r at home then probobly u have nice acoustic in the room
also important for acoustic is u'r working area
distance between the speakers and u'r chair
u'r working area (if u move to other racks that stand half meter from u'r chair while mix work)
again read some stuff on the net
there is tons of them

for clarity, when i talk about acoustics i mean how a room sounds/resonates.
what you (acidkof) mean is acoustical treatment.,
different thing
there is a lot more to acoustics than the time reflections go down by 60db,.
especially in a small room reflections can screw with your stereo image , your frequency balance and introduce phase differences in some frequencies.,
walls reflect certain frequencies better or not .,
so some frequencies will bounce through the room for a long time and give you the impression that there is a lot of that frequency in the mix.,
other frequencies will die out quickly and you will be missing them in your mix.,
some frequencies will develop standing waves.,. then you will hear the frequency in some parts of the room and not in another part of the room., waves are a strange thing,..,
so basically , acousics are a B1TCH if you're in the wrong room.,
i can't tell you how to fix acoustics but i can tell you that they make A LOT of difference.,
you will hear the difference in acoustics much much easier than a change in soundcard.,.
you can always try to rearrange your stuff in the studio.,., maybe you'll get a better sound.,
also, if you hear a lot of reflections comming from the walls (check it with a very short burst of noise) then you can put some blankets on them .,
but you DO need to trust your ears.,(as 5Meo-Geo said)
and sometimes fixing one thing will make you hear another.,,.
so it's a difficult thing.,
grts.,

I once had my studio in the same room for about three years. I don't think I ever tidied up in there, so papers, clothes, and stuff in general was all over the place - it was a mess. A hygenic mess though 
When I finally cleaned it all up, the sound from my speakers were sooo alien, and completely different. Empty, hollow, and not very "deep". I think a good balance is having some damping things in your room, and some reflecting ones. Preferably a lot of both distributed randomly.
This is the concept behind "live-end/dead-end" insulation, where you alternately have sound reflecting and sound-absorbing material on the walls...
In other words, don't work in a cement-walled room, but don't put carpets all over either

Amygdala carpets r nice but they dont do much of job
why?
well carpet is max 2 sm widht
by small calculation 0.02m=300(speed os sound)*(1/x (friquency(Hz))) u got x- 15000hz or 15 khz friquency killedby 2 sm carpet
mostly its not the friq that makes problems
usualy its more lower friqz
basstraps r used for those (by the calculation for 500hz u'll need 0.6m of acoustic trap from the wall)
actualy cement wals r good for isolation of sound outside so nothing from outside will interupt u'r work and u'r work will not hurt noone outside.
anyway noone can cover acoustic solution on the forum
invastigate some more on net

hey Meo-geo
can you please explain your formula a little bit in a clear words or provide a link, it's seems very interesting 2 me,
what a frequency and how much material to absorb it.
Tnx,

ok here its goes
G=V*T
G(gamma)
V(speed of sound)~300 m/s
T(time of 1 cycle of the sound wave)=1/friquency
now bit more about it
lets say that u have bost of 2 khz
KHz means its cycles 2000 times a second
we have to measure time that this friquency make in only 1 cycle so.....
T=1/2000 = 0.0005 seconds
now we take this T into the formula.......
G=300 (m/sec) * 0.0005 (sec) = 0.15 (m) = 15(cm)
well u should install some trap that have 15 cm of isolating material (15 cm width matress will go)
want another one???
wana try 500 hz?
G=300*(1/500)=0.6 m or 60 cm
hope its explains
boom

Hi everybody.
I was curious about the acoustics because me and my friend will set up a small amateur studio in a garage and can these egg packages help if we place them on the surrounding walls. Please note that it is an amateur studio and due to the lack of money ( here on the balkan peninsula ) we cannot afford any special material or so . Have a look :
it's the second picture from the top

excuse me for the picture I couldn't find a better example  |

it's is sure better to damp the high freqs reflection with the egg boxes than nothing.

but what about the low frequencies will they be affected too ? |

I doubt that egg boxes will do a good job but as trip said better then nothing. The egg box will not absorb the low freqs! Soft materials can absorb high freqs good, put a very thick carpet ont he wall or something. I have managed to damp some disturbing reflections (low frequencies) with pillows behind my monitors. My teacher at SAE told me that a big and soft sofa can do the trick some times when it comes to lo freqs..
Good luck!

or you can buy bass traps.
