Construction of 2 silencers at outlet of industrial fans for a flue gas treatment unit

Industrial fans occupy a place of choice for those who are concerned about the sound environment, because their operation is always accompanied by acoustic emissions which are not negligible even though they are in fairly widespread use, for many processes, as soon as it is necessary to set in motion, in various contexts, non-pressurized gases in which the noise emitted by different sound sources usually present in aeraulic networks is propagated, to which is added their self noise.

In a flue...

Compliance in terms of acoustics of a restaurant with a very low ceiling in a school

Like many other premises in the tertiary sector, school restaurants (canteens) are spaces of everyday life in which the reverberation should be limited to control ambient sound levels, for the well being of occupants that are both children and supervisory staff. It is often necessary to use in such cases special equipment in terms of architectural acoustics to ensure the habitability requirements for those spaces to which are applicable regulatory provisions related to noise limitation in...

Design of an enclosure (soundproofing hood) with low cost and reduced on site erection time for a gas turbine / combustion turbine

Among the engineering missions related to industrial soundproofing, the design of a casing (soundproofing casing) for a gas turbine / combustion turbine occupies a somewhat special place, given certain specificities.

In a power plant with gas turbines (combustion turbines), some airborne noise is emitted by the various subsets making up each turbomachinery (in addition to noise emissions associated with the mouths for air intake and exhaust not included in the current project, although...
