Acoustical sizing calculations for panels with millimetric or sub-millimetric perforations for soundproofing

Main applications of perforated acoustic panels

It is well known that perforated panels can be used as constituents of products or constructive systems for soundproofing:

  • with regard to sound absorption: for controlling the reverberation of premises (e.g. speaking and listening rooms of all kinds [1], catering areas, sports halls, offices - among which: open spaces - and industrial premises), in particular in the form of wall panels or ceiling elements or under-roof constructions...

Prediction of noise emissions from buildings and other constructions with Module 10 of the acoustic calculation software SILDIS®

The prediction of sound emissions from buildings and other constructions with Module 10 of the acoustic calculation software SILDIS® is useful when the distance at which one wishes to calculate the sound pressure level (resulting from noise transmission through walls and/or from the propagation of sounds emitted by noisy hardware installed outside, e.g. leaning against a wall or placed on a roof) is not small enough, when compared to the size of the sound sources, for them to be considered as...

Modeling of the propagation and attenuation of noise in aeraulic networks with SILDIS® software

Modeling the propagation and attenuation of noise in aeraulic networks is possible with the SILDIS® software in different contexts :

  • for air conditioning and ventilation systems (not only for applications in the building construction domain, but also in the transport sector: automobiles, trucks, trains, planes, rockets, boats and even: submarines)
  • for circuits involving air and other industrial fluids (sometimes: under pressure) of various processes (e.g. in relation to cooling, heating...
