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...

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...
