What Acouwood Ab does

Acouwood AB is a Swedish acoustic consulting firm founded in 2018 by Prof. Dr. Klas Hagberg in response to rising demand for sustainable acoustics in buildings. The firm specializes in building acoustics for structures with lightweight timber frame systems, including CLT (Cross-Laminated Timber), glulam, and wooden I-beam solutions, where low-frequency sound and impact-noise control are technically demanding. It is headquartered in Malmö with additional offices in Stockholm, Göteborg, and Umeå, and has expanded into France (Saverne) and Switzerland.

The company delivers a portfolio of six core services: acoustic building design (with BIM/REVIT integration since 2022), on-site sound measurements and verification, vibration analysis, environmental noise management, R&D on wooden building systems, and education/lectures. It holds long-term co-development partnerships with Masonite Beams and Grönbo on I-beam acoustic systems, and with Sizes Construction on modular CLT volume elements, alongside Foamglas and Ecophon SoundCircularity integrations. The team is small (approximately 9 named acousticians, including multiple PhDs and a Docent) and is differentiated by academic ties, publications in venues such as Forum Wood Building Nordic, Bygg & teknik, Husbyggaren, and RISE reports, and reference projects including Cederhusen in Stockholm (234 apartments, one of the world's largest multi-storey wooden residential buildings), the Electrolux HQ extension (BREEAM Outstanding, Noll CO2), and the Northvolt Västerås office (LEED BD+C v.4, zero CO2).

Acouwood operates a B2B, sales-led, project-based professional services model. Revenue is generated through direct consulting engagements with construction companies, architects, developers, and asset owners, typically spanning the full project lifecycle from early acoustic design through verification measurements. Pricing is not publicly disclosed; engagements are scoped per project. The firm is privately held and founder-owned, with no disclosed external funding rounds, parent company, or institutional investors.

Direct peers

• Akukon: Finnish acoustic consultancy serving building, environmental and industrial clients across the Nordics. Similar boutique specialist profile to Acouwood and a relevant competitor in cross-border Nordic mass-timber work.
• Akustikverkstan: Swedish acoustic consultancy offering building acoustics, sound measurements and environmental noise services. Closest domestic peer to Acouwood by geography, services and client base, competing for many of the same Swedish mass-timber developers and architects.
• Brekke & Strand Akustikk: Norwegian acoustic consultancy with broad building and environmental acoustics services. Comparable in size, Nordic footprint and service mix, and competes for Scandinavian mass-timber and infrastructure projects.
• Müller-BBM: One of Europe's largest independent acoustic consulting firms, with deep experience in building acoustics, environmental noise and vibration. Directly comparable to Acouwood in service scope and client type, and competes in adjacent mass-timber projects across DACH.

Broad incumbents

• Ramboll: Global engineering, design and consultancy firm with acoustics and building physics capabilities, including strong Nordic presence. Comparable where developers seek integrated engineering + acoustics offerings on mass-timber schemes.
• WSP: Global engineering consultancy with acoustics, vibration and environmental noise services integrated into multi-disciplinary building and infrastructure mandates. Competes with Acouwood on large bundled assignments, especially internationally.
• Arup: Global engineering consultancy with an established acoustics practice serving large real estate and infrastructure clients. Overlaps with Acouwood on flagship mass-timber projects but operates across many disciplines at much larger scale.

Others

• DELTA (acoustics & sensor group): Danish provider of acoustics, vibration and sensor-related testing, calibration and measurement services. Adjacent rather than directly competing: overlaps on measurement and verification work but is more product/instrument-oriented than consulting.
• Saint-Gobain Ecophon: Leading manufacturer of acoustic ceilings and wall panels, and an existing partner of Acouwood (used its SoundCircularity service). Not a consulting peer, but an enabler/supplier in the same acoustic comfort value chain and a credible ecosystem participant.
• RISE Research Institutes of Sweden: Sweden's main applied research institute, collaborating with Acouwood on timber acoustics research (HiT – Hälsa i Trä). Not a competitor, but a research and standards partner whose work directly feeds Acouwood's technical authority.
