HC ACOUSTIQUE

What HC ACOUSTIQUE does

HC ACOUSTIQUE is a French acoustic engineering consultancy founded in 2006 by Guillaume Combette and Fabrice Harlal. The firm operates from its headquarters in Lattes, with additional offices in Paris, Marseille, and Montpellier, structured as a SARL with €6,000 share capital and a small team of 1-10 employees. The company specializes in two complementary disciplines: architectural acoustics (sound insulation, reverberation control, and acoustic comfort in buildings) and electro-acoustics (sound system design and installation for venues and public spaces). Technical capabilities span sound insulation studies, reverberation correction, sound system design for spaces ranging from conference rooms to airports and train stations, and regulatory noise assessments. The firm holds OPQIBI certifications 1601 and 1604, which are COFRAC-accredited credentials required for public-sector acoustic engineering work in France, providing a regulatory barrier to entry for competitors.

The firm's service offering spans the full project lifecycle, from initial acoustic studies and 3D modeling through to on-site measurements and commissioning. Notable project engagements include work for Groupe ADP (Paris airports), SNCF (rail infrastructure), France Télévisions (broadcasting facilities), CHU Nice (hospital), and ONDIF (an architectural firm), with project values disclosed ranging from approximately €185,000 to €185 million (the latter being a major infrastructure scheme where the firm served as a sub-contractor rather than prime). International activity includes an acoustic study project in Tchad.

HC ACOUSTIQUE's business model is project-based consulting with fees structured around the scope and complexity of each engagement. The firm serves a diversified mix of public entities, architectural firms, design firms, and event organizers, with revenue concentrated in the French market. The founder-owned structure, absence of external funding, and small headcount position the firm as a specialist boutique consulting practice whose growth is constrained primarily by partner capacity rather than market demand.

Core offering

HC Acoustique is a French acoustic engineering consultancy that provides architectural acoustics consulting (acoustic design of buildings for education, healthcare, cultural, commercial, and residential facilities) and electro-acoustics and sound reinforcement services (sound management for large cultural events, noise impact studies, and acoustic modeling for safety sound systems in airports, train stations, and large venues). The firm serves as prime contractor (maître d'œuvre co-traitant) or subcontractor on construction and renovation projects from conception through completion.

Product overview

HC Acoustique is an acoustic engineering consultancy founded in 2006 by Fabrice Harlal and Guillaume Combette, offering two interconnected core services: Acoustique architecturale (Architectural Acoustics) and Électro-acoustique et sonorisation (Electro-acoustics and Sound Systems). The architectural acoustics service provides consulting and engineering assistance for acoustic design of buildings across various sectors including education, healthcare, cultural facilities, offices, and residential. The electro-acoustics service handles sound management for large cultural events, noise impact studies, and safety sound system design for venues such as airports and train stations. The agency holds OPQIBI qualifications (1601 for acoustic studies and 1604 for building acoustics engineering) accredited by COFRAC.
