AB  - This paper describes a set of design goals for the next generation of PC-based Computer-Aided Acoustic Design (CAAD) tools, given the capabilities of currently available 32-bit microprocessors, floating point coprocessors, graphics coprocessors, and near future advances in memory/mass storage systems. The CAAD tool described would allow a system designer to view a three-dimensional, animated, color-coded display while interactively adjusting parameters such as driver type, orientation, third-octave-band signal equalization, and signal delay. Various features include a three-dimensional display viewed from an arbitrarily shaped auditoria, with interactive editing of auditorium shape/dimensions; an interactive array/cluster editor to create arrays of arbitrary configuration (element type, location, and orientation); incorporation of a high resolution (two degree interval between data points) database for each potential driver, with a single optical disk used to contain an entire library of driver types; calculation of the sound field at any arbitrary surface in the acoustic space (e.g., ear plane, side wall, etc.); a swept frequency animation of the projected sound field on an arbitrarily selected surface; a time domain animation of early and late arrivals on an arbitrarily selected surface; and a display of delay differential isobars on an arbitrarily selected surface. A PC-based CAAD tool based on these design criteria is currently under development.
