I-Simpa is a graphical user interface (GUI) developed to host three-dimensional numerical codes for the modeling of sound propagation in complex geometrical domains. Although I-Simpa is well adapted for energetic models (ray-tracing, sound-particle tracing, theory of reverberation…), it can be extend to use ondulatory approaches.
I-Simpa alone is not a calculation software, but is equivalent to a pre and post-processor for acoustic codes. One or more numerical codes must be added in order to obtain a fully functional system.
At the present time, I-Simpa is delivered with two codes (TCR based on the classical theory of reverberation and SPPS based on particle tracing approach). Classical applications are room and building acoustics, environmental noise and industrial noise, but it can be easily extend to other applications concerning the sound propagation in 3D environments (interior of vehicle, sound in cavities…).
I-Simpa has been initially developed as a research tool (i.e. for research laboratories), but can also be a very efficient tool for a professional/commercial use, as well as for education.
