At any time, licensees are free to upgrade the basic package from EASE JR to. The EASE software suite consists of two different program versions and three optional modules to cover all demands of acoustical simulations, starting with professional sound system design with EASE JR to highly intricate acoustic designs of concert halls and the like with EASE Standard together with the AURA module.Īt the upcoming Prolight+Sound/Musikmesse in Frankfurt, will be releasing EASE version 4.4 acoustic simulation software that provides a host of upgrades. ELECTRO-ACOUSTIC SIMULATION SOFTWARE FOR. Stefan Feistel, AFMG managing director, explains that, “Due to the risen requirements for speech intelligibility of voice evacuation systems in all areas of public life, recent years have shown a large increase of EASE design projects from shopping malls to airport terminals, industrial plants, and even oil drilling platforms.” New version 4.4 provides expanded import/export compatibility with Trimble SketchUp, Autodesk AutoCAD and a long list of others, DXF-compatible CAD programs, as well as the update of STI calculations that are now performed according to IEC 602. It used ray tracing and image methods for auralization and incorporated scattering in the analysis.The AURA module is the most important add-on to EASE Standard.
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).
