The need to control the volume coming to the ears of those operations. Can be achieved by increasing the distance between the origin and the area where the workers live. Blocking room or a scene shelter Sound Barrier. Installing sound-absorbing materials on the ceiling or wall. Sound control practitioners. It is controlled by a worker noise exposure to a minimum.
