Heine + Jud GbR Ingenieurbüro für Umweltakustik

What Heine + Jud GbR Ingenieurbüro für Umweltakustik does

Heine + Jud GbR Ingenieurbüro für Umweltakustik is a German independent engineering and expert consulting firm specializing in environmental acoustics and noise immission protection, founded in 1994 by Thomas Heine and Axel Jud and operated as a civil law partnership (GbR). The firm operates from three offices — Stuttgart (headquarters, relocated to Alexanderstraße 23 in Stuttgart-Mitte in January 2026), Freiburg, and Dortmund — providing nationwide coverage across Germany. Its core technology comprises calibrated Class 1 sound level meters, 3-dimensional sound propagation modelling and simulation, climate and speed measurement devices, and continuous remote monitoring capability; the firm holds DAkkS accreditation per DIN EN ISO/IEC 17025 and official recognition as a measurement station under § 29b BImSchG, while two of its professionals (Thomas Heine, Stefanie Rahner) are publicly appointed and sworn experts certified by IHK Region Stuttgart.

The service portfolio spans nine consulting lines: road and rail traffic noise, commercial and industrial facilities, sports and recreation facilities, wind energy facilities, construction noise, individual private installations (e.g., heat pumps), urban development planning, noise mapping and noise action planning under the EU Environmental Noise Directive, and workplace noise. Each engagement covers the full project lifecycle from preliminary design through execution, including prediction calculations, sound level measurements, noise mitigation design (walls, enclosures, absorption), expert testimony, and support for permitting under the Federal Immission Control Act (BImSchG). Notable outcomes include Cannstatter Volksfest noise reductions of approximately 5 decibels versus 2011 baselines and over 4,000 projects completed across three decades.

Revenue is generated through project-based professional services engagements with municipalities, industrial and commercial enterprises, planning and architecture firms, sports and event operators, and private individuals. Go-to-market is sales-led: direct engagement and public-sector tender processes for municipal clients, complemented by thought-leadership positioning through vhw seminars, public hearings, and earned regional media coverage. Named clients include Stadt Stuttgart, Stadt Freiburg, Ministerium für Verkehr und Infrastruktur Baden-Württemberg, Robert Bosch GmbH, Badische Stahlwerke, SSB AG, in.Stuttgart, and Music Circus Concertbüro. The firm is entirely founder-owned, with no external investors, M&A activity, or public-market presence disclosed.

Broad incumbents

• DEKRA Automobil GmbH: Global TIC incumbent with a substantial German environmental acoustics and workplace noise practice; competes primarily on scale, geographic reach, and bundled services rather than on specialized acoustic expert testimony.
• Müller-BBM GmbH: Planegg-based, one of Germany's largest independent testing and engineering consultancies with a deep acoustics practice; competes with Heine + Jud on the same tenders but at much greater scale and with broader service lines including vibration, EMF, and building physics.
• TÜV SÜD Industrie Service GmbH: Major German testing, inspection, and certification body that bundles workplace noise, industrial noise, and environmental acoustics into a broader EHS and compliance offering, often competing for the same industrial noise measurement mandates.

Direct peers

• Masuch + Olbrisch Ingenieurgesellschaft mbH: Oststeinbek-based noise immission protection consultancy providing measurements, expert reports, and noise action planning for industry, transport, and municipalities — directly comparable service mix and German regional footprint.
• ACCON GmbH: Greifenberg-based engineering office focused on environmental acoustics, noise immission protection, and air pollution control — comparable independent expert-office model delivering measurement and prediction services to municipalities and industry across Germany.
• Möhler + Partner Ingenieure AG: Munich-based engineering consultancy specializing in building acoustics, noise immission protection, and vibration analysis with comparable measurement, prediction, and expert services across Germany — the closest direct competitor to Heine + Jud's core offering.
• Wölfel Engineering GmbH + Co. KG: Höchberg-based engineering firm with a dedicated acoustics and vibration division providing measurement, prediction, and consulting services to industrial, infrastructure, and public-sector clients, competing directly for the same noise immission tenders.
• Lärmkontor GmbH: Hamburg-based specialist in noise immission protection, urban noise mapping, and acoustic consulting for industry, transport, and events — overlapping almost entirely with Heine + Jud's service portfolio across DAkkS-equivalent testing and municipal noise action planning.
