Acoustic louvres for soundproofing

Acoustic louvres for soundproofing are appropriate when it comes (often: with little space available) to allow air renewal of a confined space (e.g. because of the presence of a noise barrier, a canopy or a sound enclosure) or even the air intake or the discharge of a ventilation network (or of an industrial process), while limiting noise propagation through the opening required in a such context.

There are therefore many situations for which acoustical louvres for soundproofing can usefully...

Silencers - new sizing possibilities for acoustics and aeraulics : ITS is looking for an industrial & commercial partner

Recent improvements to Module 1 of the acoustics calculation software SILDIS® (reported here and there) - on methods to solve with Excel the transcendental equations in relation to sound propagation in soundproofing devices for fluids (on the one hand in the channels for fluid flow that airways are, and on the other hand in the multi-layered absorbent fillings) - potentially open up new horizons for the simulation of acoustic and aeraulic silencer performance with the software SILDIS®, thus with...

Soundproofing of a hall for amplified music: dance club

Soundproofing a hall for amplified music (such as a discotheque or dancing club, a concert hall, an auditorium) is not only necessary (for the envelope of the building which must oppose sufficiently the transmissions noise), which is based on the respect of an emergence limit value i.e. the difference between the A-weighted equivalent continuous pressure levels of the ambient noise (hall for amplified music in operation) and residual noise (in the absence of the noise generated by the hall for...
