Sound mapping for non-stationary sound fields with unmatched dynamic and resolution over a broad frequency range

The Near Field Acoustic Camera allows localization and real-time analysis of
non-stationary noises such as squeaks, rattles and clicks. Unlike traditional techniques, the array of sensors does not only capture sound pressure, but the Near Field Acoustic Camera measures also directly the particle velocity. Hence, the Near Field Acoustic Camera yields accurate acoustic imaging results in the full audible frequency range, while maintaining a dynamic range and an unmatched spatial resolution.
