The prediction of performances of products and construction systems for noise control engineering often requires an approach whose nature is computationally intensive, making its application difficult for most acoustics practitioners. The software SILDIS has been developed in order to make possible such a prediction without any computational effort from users, by the means of a single PC-tool appropriate for a wide range of engineering purposes (as soon as sound propagation is concerned): in industrial sector e.g. protection of workers, preservation of environment, acoustic measurement rooms or for buildings (acoustic comfort).

Regarding the multi-disciplinary scientific and technical background, suitable approaches of all times, able to be included in the general layout of the program, have been selected and encapsulated in a easy-to-use Excel based software using drop-down menus and providing results in tabular and graphical form (French or English language) with comprehensive input/output data on a unique printable simulation report.

As far as materials are concerned (such as porous media, series cloths, series perforated protections, and thin plates), specific libraries (data bases) with more than 20 references for each kind of acoustic layer allow the design to be made with in-built engineering data (constants).

Almost all acoustics calculations are performed at single frequencies and displayed per 1/3 and/or 1/1 octave band: global values with respect to a chosen reference spectrum are computed whenever it makes sense.
