Acoustic foam are used generally to buffer sound and reduce echo and as a result most of the walls from the studios are covered with acoustic foam. This helps to keep outside sound restricted. These foams arrive in various shapes and sizes that can be attached on to the wall, ceiling, doors and so on.
