Don't get confused with the difference between sound absorption and sound proofing. Sound proofing cost alot to achive and has to do with not allowing sounds to escape your studio, again it's very expensive. Sound absorption is what your going to want to go after. Taking care of eliminating your early reflections, bass trapping and broadband absorption are not going to stop all the sound from escaping your studio (sound proofing) although it probably will lower the level coming out though. With sound proofing you'll need to have an extra wall frame with dry wall and use a mass loaded vinyl barrier between them. Again not cheap. I know you meant sound abstention and not sound proofing but just wanted to fill you in that there is a big difference between the two terms.
