What Acoustic does

Diakustic is a French boutique engineering consultancy (bureau d'études) specialised in acoustics and vibration, founded in 2002 and headquartered in Marly-le-Roi, Yvelines. The firm operates across four practice areas — Building (Bâtiment), Industry (Industrie), Environment (Environnement) and Equipment Noise (Bruit d'équipement) — providing measurement, modelling, compliance recommendations and construction follow-up through the full project lifecycle from preliminary studies (APS/APD) through to works reception (AOR). Its technical toolkit combines professional instrumentation (SOLO BLUE class 1 sonometers, calibrators, shock machines, accelerometers) with industry-standard simulation software (CADNAA/CADNAR for outdoor noise prediction, CATT ACOUSTIC 8 for 3D room acoustics, ACOUBAT SOUND 2010 for building isolation, INSUL/ZORBA for sound insulation prediction).

The firm serves a heterogeneous client base spanning French public-sector bodies (Ville de Guyancourt, APHP/Hôpital Tenon, OPAC de l'Oise, Ville d'Issy-les-Moulineaux, Ministère de la Justice, Ville de Paris/BALAS) and large private enterprises (EDF, EADS Astrium, BPB Placo, Norbert Dentressangle, Parcolog, SD Environnement, BNP, Cartier, Bobino, PSA, TOTAL/SEMARI, FREE, Telehouse/SFR/Digital Realty). Diakustic is led by founding manager Odile Mercier (ESIP, DEA acoustique) with a small core engineering bench of approximately four people including Benoit Emerald, Aldric Yung and administrative lead Caroline de Sazilly. Revenue is project-based professional services income, billed per engagement on quote-driven pricing typical of French marchés publics. The go-to-market is sales-led: direct inbound via the firm's published telephone, email and contact form on diakustic.com, augmented by responsive bidding on public procurement calls for tender. The firm is privately held, owner-operated with no external institutional investors, no parent company and no disclosed funding rounds.
