3D beamforming allows to map acoustic measuring data from the Acoustic Camera on 3D models and therefore literally adds another dimension to sound source localization. In postprocessing or while measuring the 3D model and the three-dimensional acoustic picture from the Acoustic Camera are matched using the intuitive and fast workflow of our own software NoiseImage. Any 3D model can be added to the measurement data in NoiseImage, regardless if it was created using CAD software or scanned with a laser scanner. When using gfai tech’s patented 3D acoustic imaging solution Dynabeam the 3D model and the acoustic picture are created in the same workflow eliminating the need to acquire the 3D model separately.
Our patented solution generates a 3D model while measuring the acoustic emissions at the same time. Different array positions are considered to virtually increase the channel count, reduce artefacts and raise the dynamic. Measurement positions and distances are automatically extracted from the derived scan trajectory, allowing an instant combination without any additional tracking devices or fitting requirements.
The full NoiseImage post processing functionality is directly employable allowing you to focus on your acoustic analysis. The result shows a highly dynamic acoustic image mapped on a detailed 3D model. Considering different scan directions, the main emission directivity is optionally visualized via arrows.

The NoiseImage software module Acoustic Photo 3D allows you to add another dimension to your analysis. Mapping your data in on any 3D model, either for interior measurements of all kinds or for analysing complex structures from the outside. The patented algorithm for fitting measurement object and array delivers quick and precise results. All the well-known and proved features of NoiseImage can be used with the 3D option and you can optimize your beamforming results like you are used to. One key advantage of 3D beamforming is that the acoustic images are calculated based on the distances between microphone array and meshes / points hence the calculation takes several focus layers into account. That way beamforming in 360° around the array is possible. Furthermore single or multi array measurements of any object from the outside mapped on a 3D model will be more precise.

The NoiseImage module Advanced Algorithms holds all its features ready for the 3D analysis and allows you to optimize your results. Due to the several focus layers which are taken into account you can expect better results for scenarios with sound sources in different distances.
