Modeling of dissipative silencers - refinement of the calculation of acoustic performance - SILDIS® software

The modeling of dissipative silencers is often considered as a tedious task by the practitioners of acoustics, in relation on the one hand to the high number and the great variety of the phenomena having to be taken into account, and on the other hand in relation to the difficulty to be in a position of using calculation means adapted to a dimensioning context which must (quite often), as far as possible, be carried out with little effort and within a short timeframe (e.g. when the context is...

Acoustics and aeraulics - 9 minutes are enough for the complete calculation of a silencer with the SILDIS® software: the proof in video

In terms of calculation for acoustics and aeraulics, the SILDIS® software combines ease of use, speed of simulation, versatility and reliability for the sizing of silencers with possible applications in the building sector e.g. Heating Ventilation Air Conditioning (HVAC) ) and in industry, e.g. aeraulic networks with fans or even including the intake and exhaust of turbomachines (compressors, turbines) and heat engines, as well as processes involving pressurized fluid systems (including at high...

Insulation - simulation of sound transmission (or sound reduction) of acoustic multilayered structures (plane partition i.e. flat walls and envelopes of aeraulic networks or pressurized fluids) with the SILDIS® software

In the field of insulation, the simulation of sound transmission (or sound reduction) of multilayered acoustic structures (plane partitions i.e. flat walls and envelopes of aeraulic or pressurized fluids networks) is fundamental, since it is the basis of the design of construction systems opposing noise propagation, which is sought after in many contexts.

This is why the evaluation of sound transmission (or sound reduction) through multilayered acoustic structures is a fairly recurrent task...
