ABSTRACT:
A wall-mountable acoustic device for absorption of sound in an indoor area is constructed of self-supporting interbonded rockwool mat material. The primary component made of the mat material is shaped in semi-cylindrical configuration. End panels of rockwool mat of similar composition are attached to the opposite ends of the semi-cylindrical configuration to enclose the configuration except for an open rear extremity of rectangular perimeter. When attached to a flat wall, a totally enclosed semi-cylindrical chamber is defined. In a preferred embodiment, further improvement of sound absorption properties is achieved by way of a diaphragm disposed within the semi-cylindrical configuration.
