OMG!
How do I go about doing this?

The room I'm in is 13x15x8. I have my desk centered on the 13' wall. All the walls are drywalled and there are two windows on the wall behind me. Theres carpet on the floor too.

How would I go about determining the amount of treatment needed?

I was going to put bass traps in all the corners... but the wall to my left has a door that is about 4" away from the rear wall. Also, for the front walls, there are outlets where the traps would be going out... would i just run an extension cord out from behind it?
 
Ethan Winer's site recommends putting bass traps in all the corners at a minimum. Of course, we end up doing what we can given the space and money available. You probably need some absortion too, but determining how much is not always easy. Hopefully some of the experts will chime in.

I also have a door near one of the corners of my room. I put the bass trap as close to the door as possible and called it good. When I ran into the outlet problem, I just made the bass trap a little shorter; my outlets are all about 12" from the floor.

Ethan's web site is a good place to start http://www.ethanwiner.com/acoustics.html

You can also go to the aurelex web site. I've heard that you can send in your room dimensions and they will recommend the treatment you need.
 
I've read a majority of that article. I was curious if there was a way to determine the right/minimum amount of treatment for your room.

I dunno. I won't be able to do it til I get money anyway. I need monitors first.
 
Old school

There are allot of Pro's on this board that will throw calculations and spreadsheets at you (nothing wrong with that, I just don't have time). I take an old school approach and try different things when recording, placement of traps, fiberglass panels, blankets, whatever and when it sounds good to me I press record. I am happy to spend more time recording and less time calculating.
 
Geet,

You want as much absorption as possible below about 300 Hz, and a lesser amount at mid and high frequencies. Unless you want to get into the complication of measuring your room, just start with bass trapping in the corners and add more treatment later if you think it's needed.

Thank you. I was assuming that the amount of treatment needed for a room was kind of subjective. I guess it just depends on what I feel the room needs to be sufficient.

Thank you Mr. Ethan Winer.
