What Topsonic does

Topsonic Systemhaus GmbH is a German provider of flight noise monitoring (Fluglärmüberwachung) and flight track surveillance (Flugspurüberwachung) systems for airports, founded in 1994 and headquartered in Würselen, Germany. The company operates as a privately held subsidiary within the AirITSystems aviation IT group and runs with a small team of 11-50 employees, despite having systems deployed at 15+ major international airports across Europe, South America, and Asia. Its core offering is the TraVis web-based platform, which integrates real-time aircraft tracking with noise measurement terminals, GIS visualization, complaint management, and configurable public portals. TraVis supports multi-language interfaces (German, English, French, Dutch, Spanish), adjustable live-data delay settings per airport requirements, and AzB2008-compliant noise calculation algorithms with ±3 dB(A) accuracy near flight paths. Ancillary modules include AirportRadar for surface movement visualization, dedicated noise monitoring stations (fixed and mobile), and a community management interface for resident complaint handling. A Sky Cast AI feature uses neural networks to forecast airport operating directions based on comprehensive weather data, first deployed at London Luton.

The company generates revenue through a hybrid model combining one-time licensing of hardware and software deployments (measurement stations, sensors, TraVis configuration, installation, and commissioning) with recurring modular maintenance contracts ('Wartungsstufen') that cover software updates, calibration, and ongoing support. A community management professional services stream supports complaint handling systems and public reporting portals. Pricing is project-based and quote-driven, segmented to airport size and system complexity. Topsonic's go-to-market is direct enterprise sales into airport operators and aviation authorities on a consultative, project basis, with marketing support from its topsonic.aero website, industry conferences (inter.noise, inter airport Europe), and university career fair participation for talent acquisition.

The customer base is concentrated in civilian commercial airports, with secondary exposure to military airbases and aviation regulatory bodies; named customers include Frankfurt, Munich, Berlin Brandenburg, Hamburg, Düsseldorf, Cologne/Bonn, Stuttgart, Hannover, Leipzig/Halle, Vienna-Schwechat, Prague, London Luton, Brussels, EuroAirport Basel-Mulhouse-Freiburg, Indira Gandhi Delhi, Manohar Goa, Santiago de Chile, Lima, Graz, Dresden, and Ørland Airbase. The company has continued to expand internationally, most recently deploying new systems at three Greek airports in 2024.

Direct peers

• Brüel & Kjær (HBK): HBK (Hottinger Brüel & Kjær) is a global leader in sound and vibration measurement, including airport and environmental noise monitoring systems. It is the most direct competitor to Topsonic's noise monitoring terminals and calculation algorithms, serving the same airport customer base.
• Norsonic (NDB Technologies): Norsonic is a Norwegian manufacturer of sound level meters, noise monitoring terminals, and building acoustics instrumentation, directly comparable to the hardware/software stack Topsonic deploys at airports.
• Cirrus Research: UK-based manufacturer of noise monitoring instruments, sound level meters, and outdoor noise monitoring systems used in environmental and airport applications, overlapping directly with Topsonic's product offering.
• 01dB (ACOEM): ACOEM's 01dB brand produces noise and vibration monitoring solutions, including outdoor monitoring terminals and environmental noise software, competing in the same airport noise monitoring segment as Topsonic.
• SVANTEK: Polish manufacturer of professional sound level meters, noise dosimeters, and environmental noise monitoring systems, with comparable product depth to Topsonic in measurement hardware and software.
• Casella (IDEAL Industries): Casella, part of IDEAL Industries, manufactures noise monitoring equipment and environmental noise software (NoiseTools), serving occupational, environmental, and airport noise monitoring markets comparable to Topsonic.
