NoiseImage is gfai tech's modular software platform for acoustic data acquisition, analysis, visualization, and reporting. It combines multiple sound source localization methods—delay-and-sum beamforming in both time and frequency domains, nearfield acoustical holography (SONAH and HELS), and sound intensity mapping—within a single user environment. GPU acceleration enables real-time acoustic imaging at frame rates up to 192,000 fps, displayed as colour-mapped overlays on still photos or navigable 3D CAD and point-cloud models of the test object.

What acoustic mapping methods does NoiseImage combine?

The platform supports the full range of acoustic imaging techniques. Time-domain and frequency-domain beamforming localize broadband and transient sources at mid-to-far field distances. Nearfield holography (SONAH/HELS) reconstructs sound pressure, particle velocity, and intensity fields at low frequencies where beamforming resolution degrades. The psychoacoustics module maps perceptual metrics—loudness, sharpness, roughness, tonality—directly onto the test geometry, translating physical sound fields into human hearing-relevant quantities for automotive and consumer product NVH refinement.

How does NoiseImage handle specialized test scenarios?

A plug-in architecture delivers application-specific capabilities without bloating the core interface. The Wind Tunnel module applies shear-layer and wind-speed corrections for aeroacoustic measurements in open-jet and closed-section facilities. The PassBy module performs panoramic acoustic imaging of moving vehicles with automatic Doppler correction and speed profile calculation for ISO 362 and UN R51.1 compliance testing. The Order Analysis module extracts order spectra, ordergrams, and order-based acoustic movies for rotating machinery diagnostics—fans, motors, gearboxes, and drivetrains. An integrated Project Manager executes batch processing runs and generates automated PowerPoint reports for standardized test documentation.

Frequently Asked Questions

Can NoiseImage process data from non-gfai tech hardware?

Yes. The Import/Export module ingests time-domain data in ATFX and UFF58 formats from third-party acoustic cameras and microphone arrays. Results export to WAV, HDF, TXT, MATLAB, and standard image formats for downstream processing in external tools.

Does NoiseImage support custom algorithms?

Yes. The C++ and MATLAB interface modules allow users to integrate proprietary beamforming algorithms, filters, or post-processing routines as DLL plugins that run within the native NoiseImage processing pipeline.
