ABSTRACT:
An acoustical diffuser is disclosed for diffusing sound. A preferred diffuser includes a first fibrous material, a first separator layer, a diffuser material a second separator layer, a second fibrous material and an acoustically transparent material. The subject invention also includes a preferred method of molding such diffuser. The subject invention further includes a panel that has an acoustically reflective side and an acoustically transparent side over a frequency range that can be attached to the walls of a room to enhance the acoustical characteristics of the room. A preferred method of installing such panels includes installing fabric retainer members to the walls between the panels and attaching an acoustically transparent material to the fabric retainer members such that the panels and fabric retainers are covered by the acoustically transparent material. The panels may preferably be arranged such that acoustically reflective surfaces on one wall oppose acoustically absorptive surfaces on another opposing wall. Preferably, panels are attached to the walls such that the acoustically absorptive surfaces thereof are facing the room interior where the walls abut each other to form corners. An acoustical built-in wall system and an acoustical door and method of applying an acoustical treatment to a door are also disclosed.
