![]() ![]() It used ray tracing and image methods for auralization and incorporated scattering in the analysis. ![]() ![]() CAESAR used ray tracing to predict acoustical parameters. From 1998 to 2001, another important analysis program, CAESAR, was developed by Michael Vorländer and Andreas Schmitz of Aachen University in Germany. 3.0, the first version designed for Windows 95/NT/ME/2000 was released by Ahnert, Stefan Feistel, and Rainer Feistel. That same year, ADA released EASE’s first version, a full graphic MS-DOS-based CAD program for acoustical analysis. Since receiving his PhD, Ahnert has been a professor at the Hochschule für Film und Fernsehen (Academy for Film and Television) in Potsdam-Babelsberg, Germany. In 1990, Ahnert founded the Engineering Office Acoustic Design Ahnert (ADA). ![]() He co-authored a book on architectural acoustics in 1980, and has published numerous books and papers. Beginning in 1975, he worked as a consultant planning theaters, concert halls, and other cultural buildings. Wolfgang Ahnert, the initial developer of Enhanced Acoustic Simulator for Engineers (EASE), studied technical acoustics at the Technical University Dresden and at the Moscow State University (Lomonossov). The EASE software suite provides system designers and consultants with an invaluable set of tools for all aspects of professional practice, from detailed, realistic modeling and simulation of venue acoustics and sound system performance to informative and engaging client presentations, as well as professional data assessment and verification. ![]()
