ABSTRACT:
The sound absorbing and diffusing unit is provided for assembling an acoustic screen which can be placed or hung in front of a wall inside an acoustic room for improving a sound-effect therein. These units are detachably joined together with each other so that they may be easily separated and assembled again to form an acoustic screen having another shape or construction to adjust or modulate a sound-effect. A sound absorbing porous panel having a desired picture or pattern can be easily hung against a wall. The decorative panel can be reversely hung on the wall to provide another interior ornamentation. Accordingly, an acoustically correct room and a desired ornamentation on a wall inside the acoustic room can be easily obtained and changed without providing a rigid reverberating surface of the room.
