Improvement of the acoustic ambiance of a restaurant in an enterprise / a cafeteria by the means of perfectly matched acoustical screens (absorbing claustras) and absorbing wall lining

Like many other premises in the tertiary sector, restaurants in enterprises (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 users and service 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...

Soundproofing of 4 test benches for combustion engines with high power output

In a factory producing machines, engines on which technical checks are performed (e.g. endurance, requiring a specific test bench) is a very powerful noise source potentially causing sound nuisance for personnel operating in the vicinity as well as for the neighborhood. It is often necessary to use in such cases a very performing soundproofing equipment in order to ensure compliance of the installation on the one hand with respect to the legislation on noise at work and on the other hand with...

Study and sizing of an exhaust silencer for a gas turbine / combustion turbine

In a power plant with gas turbines (combustion turbines), exhaust is a very powerful noise source potentially causing sound nuisance for personnel of the operator operating in the vicinity as well as for the neighborhood (including long distance, a fortiori in the case of tall stacks). It is often necessary to use in such cases a soundproofing equipment of high technology to ensure compliance of the installation on the one hand with respect to the legislation on noise at work and on the other...
