If you want cheap sound proofing and sound dissipation, put some potted plants in the corners and hang some things in all the ceiling corners. That will help quite a bit. You can use rockwool (heat insulation) and cover it with a curtain (to stop the dust and help with sound absorption) for the walls. Even better if you can hang it 1 cm from the wall!
