Room Acoustic Treatment

After long searching, finally settled down with Roxul MPS400 1" thick insulation material (Density: 80kg/m3). Per pack of 12 sheets (size of 4' x2') cost me around RM100. MPS400 is a non-combustible and firesafe material. My advise don't look for cheap egg crate for acoustic treatment, fire risk is something you should avoid at all cost.

My dad has been a great help to me in making the sound traps. He is such a great carpenter and at the age of 71, still got the strength to saw and nail. I must admit that my carpentry skill is no way close to him.
