The power of the Closet

Hello! I'm far away from build my own studio. Currenly I'm using my bed room as home studio. I think this could be a stupid question, I don't know. :oops: I have a closet that fills the wall behind me (when I sit at the desk). What is the power of absorption of a closet full of dresses? Another thing: if I keep the closet open I feel a little strange while monitoring. It seems like to be in a anaechoic chamber. Ehm, don't take care of the quality of the picture below. ;) MaxB
