Our sound source localization (SSL) solutions help you visualize sound directly at the source. Typical applications of SSL are troubleshooting noise issues, comparing the acoustic performance of product variants, and confirming subjective sound assessments with objective data. With SSL, ensure you work on the right problem before fixing it.
Our Simcenter Sound Camera system is a modular, high-quality digital microphone array that offers an instant overview of sound sources on any noise-generating object. It is a great tool for both occasional and expert users to accelerate acoustic troubleshooting. The system's design includes arms that can be added or removed, making the camera a great tool for multiple test conditions.
Advanced sound source localization methods can improve results accuracy compared to traditional beamforming. These methods are called focalization, irregular nearfield acoustic holography, deconvolution-based methods, and inverse-based methods like Bayesian focusing.
Bayesian focusing is a microphone array method that outperforms traditional methods both in sound source localization and quantification. It covers the full frequency range and allows a wider distance to the source compared to traditional methods. It works both for correlated and uncorrelated sources, contrary to other wide-band methods. Finally, it also delivers quantified results.
Our 3D Acoustic Camera is a spherical microphone array that provides insight into the noise structures of an interior cavity like a vehicle cockpit. A geometry scanner quickly scans the interior volume with a resolution suited for acoustic analysis. It then uses spherical beamforming to visualize sound sources directly on the geometry of that cavity. It is also capable to analyze the sound power contributions of the sources in the entire cavity, or of partial components. These can either be visualized as sources on the 3D hologram or as sound power spectra for comparison.
Soundbrush, our 3D real-time acoustic troubleshooting solution combines 3D sound intensity with sound source localization. It allows you to visualize exactly what you hear and provides detailed, immediate results for easy identification of noise sources including sound intensity values, sound propagation directions, and sound power values.
