Uncertainty pervades the room acoustic problem: there is uncertainty in measurement and characterization of materials, uncer- tainty in the models used for propagation and room interaction, uncertainty in the measurement of sound within rooms, and uncertainty in perception. Only recently are the standard methods of uncertainty assessment being systematically employed within room acoustics. This paper explains the need for systematic study of uncertainty in room acoustic predictions and review some of the most recent research related to characterizing uncertainty in room acoustics. 8:40 2aAA2.
