Acoustic Evaluation and Assessment of Offices and Public Rooms with the STI-Matrix Method

摘要

Human speech is one of the most important "noise sources" in open plan offices, restaurants and other rooms where communication between people is important. With existing software techniques, it is possible to create computer models of such environments in the planning phase and to apply measures with an optimized layout to ensure that intelligibility is optimized according to clear formulated targets. The STI-Matrix technique supports the study of every speaker-to-listener combinations within a room, so the best conditions are met. This contribution presents the technique demonstrated for a planned restaurant where multiple conditions should be fulfilled.
