acoustically separate space

an occupied space such as a room or a part of a contiguous area, where the acoustic properties are different from other parts. These differences may be due to variations in ceiling height and/or width by more than 20 percent or where the floor covering changes from carpet to hard tiles, stone or concrete cement or where the reverberation time changes by more than 30 percent for other reasons
