A system for knowledge‐based architectural acoustics

The concept of knowledge‐based architectural acoustics is proposed showing a prototype of an intelligent system for room acoustic design as a practical example. The system is composed of two major subsystems, an acoustic field simulator and an expert system for room acoustics. The principal objective of the system is to assist acoustic designing. This system can also be used for training acoustic designers and for evaluating both design policies and design parameters to represent the physical characteristics and subjective aspects of sound fields, such as spaciousness and definition. The field simulator is utilized effectively by refining the calculation algorithms and checking whether the performance coincides with actual fields. The validity of the design parameters is examined by listening to the output sounds of the field simulator. Some examples of the system's performance on rooms with simple shapes are shown, and the principle of evaluating subjective design parameters is indicated.
