What ORFEA Acoustique does

ORFEA Acoustique is an independent French acoustic engineering and consulting firm headquartered in Brive-la-Gaillarde, operating through nine regional agencies across France (Paris, Lyon, Bordeaux, Rennes, Metz, Clermont-Ferrand, Limoges, Valence, and Brive). Founded in 1997 by Frédéric Lafage, the firm is currently led by President Grégory Kohen and specializes in noise and vibration studies across six vertical domains: Building, Industry, Environment, Wind Energy, Land Transport, and Urban Areas.

The firm's service portfolio centers on Études Acoustiques et Vibratoires (acoustic and vibratory studies) and Conseil et Accompagnement (advisory and support), covering initial diagnostics, predictive impact simulations, on-site measurements using sonometers (Acoem, Sigicom brands), workplace dosimetry, GIS-based sound mapping, 3D computer simulation, and regulatory compliance validation. Service delivery spans the full project lifecycle from conception to acceptance testing. Clients include public authorities, architects, engineering firms, industrial operators, energy developers, and property developers, with named engagements spanning EDF/Northland Power's Saint-Nazaire offshore wind farm, TELT's Lyon-Turin tunnel, RTE's high-voltage power line framework, the French Ministry of Defence, SNCF's railway maintenance facilities, Volvic (Danone), Crédit Agricole Centre Ouest, and Basic-Fit Europe (200 studies across 1,000+ clubs).

Revenue is generated through project-based B2B consulting fees, individual project commissions, and multi-year framework agreements. The firm reports more than 600 clients annually and several thousand cumulative studies. Distribution is direct via the nine-agency network; the firm is not an aggregator or marketplace. The company is structured as a SAS (Société par Actions Simplifiée) with €163,236 share capital, is privately held with no external investment and no parent company, and has announced a 2026 plan to recruit approximately ten acousticians plus a similar cohort of alternates.
