Acoustics – Design and sizing of plate resonators with circular, square or slotted perforations or not perforated (for silencers and absorbing linings) with software SILDIS®

Wisely used, resonators can make the lives of acoustics practitioners easier, if they have a reliable and user-friendly decision-making tool allowing them to solidly base, adjust (and personalize ?) the solutions they provide to problems relating to sound comfort improvement and to noise reduction (with a competitive advantage ?).

The software SILDIS® allows the sizing of plate resonators with circular, square or slotted perforations, or even not perforated for the design of soundproofing...

Practices, evolutions and trends for acoustical design in the construction sector, in relation to the developments of Computer Aided Design (CAD)

Overview in May 2020

When it comes to acoustics, design tasks in the construction sector are often complex, wether it comes to Research and Development (R&D) works or to engineerings tasks.

Until recently, they were based (e.g. for what realtes to the evaluation of performance indicators in terms of sound transmission through walls, sound absorption, limitation of noise propagation in ducts) on technical data possibly coming from two operating modes (and not one more), each one being...

Acoustics - simulation software SILDIS® – silencers sizing online

When it comes to acoustics, as described here and there, the Module 1 of the simulation software SILDIS® allows the sizing of silencers, for applications on the one hand in the building sector e.g. Heating Ventilation Air Conditioning (HVAC) facilities and on the other hand in the industrial sector e.g. aeraulic for air intake and exhaust of fans, combustion engines, turbomachinery by allowing (from input data relating to geometry, thermodynamics, fluid mechanics, and taking into...
