gfai tech offers customized solutions for a wide range of measurement scenarios. Whether fixed installations in a test stand, mobile arrays with flexible floor anchoring, or microphone systems with mounting options for overhead cranes - the experts at gfai tech will find a cost-effective solution for you.
Using in-house optimization software, the optimal microphone array can be developed for any measurement scenario. By constructing the arrays from waterjet-cut aluminum plates, the determined microphone distribution can be realized. Emphasis is placed on acoustic transparency throughout the design process. Thus, despite their size, our arrays hardly influence the acoustic properties of the environment.
From simulation to design and manufacturing, gfai tech accompanies you on your way to a unique product.
The customised foldable Evo-Array was developed for the localisation of vibro-acoustic phenomena on gear boxes for wind turbines at Flender GmbH. Equipped with 72 microphones and additional channels for RPM and acceleration , it enables precise order analyses on rotating machines. Thanks to flexible positioning and fast integration into test benches, we deliver high-resolution acoustic data - even at changing speeds. For developers, this means in-depth insights into the dynamic behaviour of gearboxes, optimised designs and measurable progress in performance and resource efficiency.
The Helianthus168 array is a customised solution for aero-acoustic research. Developed for wind tunnel experiments at RWTH Aachen University, this highly sensitive microphone array with 168 microphones arranged in a spiral enables complex flow and sound phenomena to be analysed precisely. Using the powerful NoiseImage Pro analysis software and special software modules in the wind tunnel, source localisation is optimised with beamforming methods. Thanks to its precise measurement accuracy, wide range of applications and user-friendly handling, we are setting new standards for customised hardware solutions in the field of aerospace technology.
