Now, the modules of the ITS acoustic calculation software, SILDIS®, in Excel format, are with a near-perpetual license (100 years). They allow the prediction of the acoustic performance of cosntruction systems designed for sound absorption/attenuation, and of the impact of sound sources (by modeling sound propagation) for various applications in the field of soundproofing (building and industry):

  • Prediction of the acoustic and aerodynamic performance of dissipative or resonant silencers...

Sound absorption/attenuation - Modeling of hybrid resonators with CAD software SILDIS®

Details

Resonators are devices based on different construction systems designed for sound absorption/attenuation for a variety of applications in the field of acoustic insulation, in both the building and industrial sectors:

  • sound absorbing linings for acoustic treatment of premises (i.e. to reduce sound reverberation, e.g. living spaces, speech and listening rooms, test benches and acoustic measurement rooms)
  • silencers liners (to limit the transmission of noise from aeraulic ducts e.g. air intake...

Computation of silencers with alternate splitter baffles orientation

Details

Reducing noise in industrial air networks is an issue with considerable technical and financial stakes, particularly in the case of large cross sections (often rectangular or even square) through which a fluid is transported with a very high flow rate, such as for example in the case of projects including large diameter fans (of the order of 10 m for some cooling towers) or turbomachines (large capacity compressors, combustion turbines even of average power) with regard to both air intake and...
