BeSB GmbH Berlin

What BeSB GmbH Berlin does

BeSB GmbH Berlin, formally BeSB GmbH Berlin Schalltechnisches Büro, is a privately held engineering consultancy founded in 1980 by Prof. Dr.-Ing. Edelbert Schaffert and headquartered in Berlin (Undinestr. 43, 12203 Berlin). The firm delivers specialized services in sound and vibration technology — acoustic and vibration measurements, computer-based prediction calculations, qualified expert opinions, continuous (24/7) monitoring, planning support, and the development of noise-optimized operating concepts — to enterprise and institutional clients across German-speaking Europe with limited project work in France, Austria, and Bulgaria. Customer verticals span industry and commerce, airports and aviation, ports and logistics, motorsport and test tracks, sports venues, construction and infrastructure, transportation, urban planning, occupational health, machine manufacturers, and sensitive facilities such as museums.

Underlying capability rests on proprietary technology: computer-based noise prediction and sound-monitoring software, an in-house semi-anechoic testing room, a multi-decade accumulated internal emission database, and custom-developed multi-channel measurement and sensor hardware, including foreign-noise filtering software deployed at facilities such as HHLA Container Terminal CTA Hamburg and a scalable permanent measurement network reaching 23 three-channel stations. The firm operates a separate sonification product line — Swim Smart, SONATA, and Sofirow — that converts motion-sensor data into real-time audio feedback for sports training and neurological rehabilitation, developed with academic partners including Universität Hamburg and the University of Toronto. Three officially recognized credentials underpin tender eligibility: a § 29b BImSchG measurement station appointment, VMPA recognition for DIN 4109 building-acoustic testing, and DAkkS accreditation under DIN EN ISO/IEC 17025, alongside a publicly appointed and sworn court expert for room and building acoustics.

BeSB generates revenue from project-based, quote-priced professional services contracts; pricing is not publicly disclosed and engagements are scope-tailored rather than package-based. The firm is led by two managing directors, Dipl.-Ing. Alexander Knobloch and M.A. Johannes Scheller, with the founder chairing an advisory board; total headcount is approximately ten employees including project engineers and computer specialists (firmographics). Customer acquisition is primarily reputation-driven through enterprise field sales with no indirect channels or reseller distribution and only a limited digital presence via the company website.

Core offering

BeSB GmbH Berlin Schalltechnisches Büro delivers specialized engineering consulting in sound and vibration technology, covering acoustic and vibration measurements, computer-based prediction calculations, expert opinions, 24/7 sound and vibration monitoring, planning, and the development of noise-optimized operating concepts. The firm operates seven service lines — immission control, building and room acoustics, vibration engineering, machine acoustics, race and test track acoustics, occupational noise protection, and sonification-based sensor/audio systems — supported by its own semi-anechoic chamber, proprietary software, permanent measurement stations, and accredited testing-laboratory status.

Product overview

BeSB GmbH Berlin is a specialized acoustic and vibration engineering consultancy offering a comprehensive portfolio of services centered around noise protection, building/room acoustics, vibration engineering, machine acoustics, race track planning, occupational safety, and sonification technology. The core offering consists of consulting and measurement services for regulatory compliance and technical problem-solving. The Sonifikation division represents a distinct product line featuring proprietary sensor-based systems—Swim Smart, SONATA, and Sofirow—that convert motion data into real-time audio feedback for sports training and medical rehabilitation. All services are backed by in-house technical development including proprietary software for noise prognosis and monitoring, and a semi-anechoic testing facility.

Overlaps with BeSB's measurement and consulting capabilities but operates globally and primarily as a measurement-instrument manufacturer, not a niche consultancy.
• PCB Piezotronics, Inc. PCB Piezotronics is a major U.S. manufacturer of piezoelectric sensors, accelerometers, and vibration measurement instrumentation used in industrial, aerospace, and automotive applications. Comparable to BeSB's vibration measurement and analysis capabilities but operates as a global instrumentation vendor rather than a specialty consultancy.
• Cirrus Research plc (formerly Norsonic): Cirrus Research, having acquired Norsonic, is a UK/Scandinavia-based manufacturer of acoustic measurement instruments and provider of occupational and environmental noise monitoring services.
