Since my stereo room has no carpet and the paint on the wall is pretty hard, i decided to make something cheap to absorpt sound.
Material:
1 piece of foam(about 2"x96"x24"), $7.79 from HxxxDepot.
1 piece of soft cotton, $2.38 from WxxMart.
1 piece of cloth, $7.59 from WxxMart
all the above were cut into 4 equally.
Step 1: cover the foam with a piece of soft cotton to increase the efficiency of sound absorption.
Step 2: then cover with the other layer, cloth.
