Abstract : Whatever for indoor noise applications (room acoustics, noise in vehicles...) or sound propagation in the environment (open field, urban areas...), many numerical codes have been developed by researchers. Most of them have many common aspects, like the definition of the domain geometry and the materials (boundary conditions, impedance...), the definition of sound sources and of receivers (position, spectrum, directivity...). Moreover, they all have the same objective that is to predict the sound field within the domain, with several acoustics indicators, like acoustic pressure or sound levels, and through several representations (impulse response, spectrum...). In order to make easier the use of such codes (pre and post-processing of data), as well as for facilitating comparisons between models, a specific graphical user interface (I-Simpa) was developed specifically. In addition to previously cited facilities, this tool allows users to implement their own numerical models, as well as to manipulate the interface and to develop specific treatments by creating built-in Python(TM) scripts. As example, the paper will present the implementation of an energetic model for room acoustics predictions. The final objective is to create a community around this tool in order to exchange numerical codes, scripts... and information.
