Soundproof Home studio !

[toine6]

Thank you guys for all the information!! looks like i will have to keep it at low volume while mixingdown! one quick question ! what will happen if i cover my room with Fiberglass Owens corning 703 (3 inch thick). will it at least help reduce the amount of db coming out of my room ? i was thinking of making fiberglass panels, and just put them all around the room! i will also buy for monitors acoustic foam isolator to prevent vibrations!

Careful with fibreglass, its dust can be awful for your lungs.

I found this website which could give you some ideas.

COPY AND PASTED because I'm too lazy to type it out.

"What does Acoustic Treatment do?
Many people think acoustic treatment is for "soundproofing" their room. Actually, that is not the case at all. What foam does is absorb high frequencies bouncing around the room and gives your studio a "deader" sound, with fewer reflections. It allows for microphones to pic up the sound more directly from the instrument being recorded and it allows you to hear what is coming out of your monitors without ringing frequencies. To absorb some of the excess bass energies, bass traps are put in corners to help reduce 'standing waves" or resonant bass frequencies. In sum, good use of foam can quiet your room of things you don't want to hear. "

it's not good for the skin either, I call it itchulation

Drywall is what you want. It will help some to add a layer or two to all walls (and possibly floor and ceiling depending on where you live).

thanks guys !! i did some research and found somthing. STC whic is the amound of db could be absorbed in the material the higher it gets the more db it kills.. so basicallsi a Material with 30 STC can lower block waves up to 40 db! pretty cool ha? however, its really hard to find material that has high stc and can be afforded. if you ever find something cheap with high stc please inform me!! thanks again guys

well, read what has been said in this thread then take this for what it is because it's wiki (especially the part in bold) ...but apparently if you take the advice offered hear with just drywall and a room within a room and get an STC of 63

http://en.wikipedia.org/wiki/Sound_transmission_class

Sound damping techniques

Typical interior walls in homes (1 sheet of 1/2″ drywall on either side of a wood stud frame) have an STC of about 33. When asked to rate their acoustical performance, people often describe these walls as "paper thin." They offer little in the way of privacy. Adding absorptive insulation (e.g., fiberglass batts) in the wall cavity increases the STC to 36-39, depending on stud and screw spacing. Doubling up the drywall in addition to insulation can yield STC 41-45, provided the wall gaps and penetrations are sealed properly.[citation needed]

Note that doubling the mass of a partition does not double the STC. Doubling the mass (going from two total sheets of drywall to four, for instance) typically adds 5-6 points to the STC. Breaking the vibration paths by decoupling the panels from each other will increase transmission loss much more effectively than simply adding more and more mass to a monolithic wall/floor/ceiling assembly.[citation needed]

Structurally decoupling the drywall panels from each other (by using resilient channel, steel studs, a staggered-stud wall, or a double stud wall) can yield an STC as high as 63 or more for a double stud wall (see table below), with good low-frequency transmission loss as well. Compared to the baseline wall of STC 33, an STC 63 wall will transmit only 1/1000 as much sound energy, seem 88 percent quieter and will render most frequencies inaudible.

FWIW Whisper rooms are big bucks and here's what you get...(of course if you can keep the whisper room separate from other walls, the floor and ceiling you'll get some of the benefits of a room within a room).

(standard model starting at 3,100usd to about 15k depending on size)
Frequency (Hz): 125 250 500 1000 2000 4000
Reduction (dB): 29 36 43 45 48 52

(Enhanced model starts at around 5,600usd to almost 30k)
Frequency (Hz): 125 250 500 1000 2000 4000
Reduction (dB): 30 44 53 61 67 68

Bottom line is you live in an apartment and with it comes limitations...oh how well I know and there is no inexpensive way around it...there's no magic material, "no lost in space force field", it's mostly in the construction and that's not cheap nor something a landlord will be to eager to allow
