    Acoustic measurement methods

    The various resources available (anechoic chamber, microphones, acoustic arrays,…) can measure the acoustic emissions of the components of vehicles or others, with the main objective of reducing noise nuisance.

    Our characterisation benches for materials and silencers let us measure the efficiency of absorbent materials and the effectiveness of silencers (exhaust, input) for engines.

    This equipment can be made available via a partnership platform to allow industrialists to realise their research and development projects..
