Beschreibung

In the acoustic design of concert halls, auditoriums and openplan offices, speech intelligibility (STI) plays a decisive role in evaluating the quality of a room from an acoustic point of view. The speech intelligibility index has established itself as an attractive parameter in the scientific environment. For an effective design of such rooms, simulation models are used to lay out room design and interior construction at an early stage and to define optimal conditions even before the actual construction. Here, the so-called ray-tracing method is state of the art, which considers acoustics as an analogy
to optics. The adjacent illustrations show the propagation of sound rays in a concert hall at t0 = 0s, t1 = 5ms, and t2 = 30ms. The task of the project includes the further development of an
existing simulation models to enable STI mapping and to include psycho-acoustic parameters. For this purpose, the simulation tool Comsol Multiphysics together with Matlab is available. The goal
is to visualize an STI landscape in a simplified model of an office.
