Near-Field Acoustic Camera
SOUND VISUALIZATION WITH UNMATCHED DYNAMIC RANGE
Our system stands apart from traditional techniques by employing an array of PU sound intensity probes that capture more than just sound pressure. As a result, the Near-Field Acoustic Camera delivers precise acoustic emission results as well as detailed noise localization maps across the full audible frequency range. It accomplishes this while simultaneously maintaining an exceptional dynamic range, achieving unparalleled spatial resolution even for low-frequency noise sources.

Product Overview
UNPARALLELED LOW-FREQUENCY SOUND LOCALIZATION IN THE NEAR-FIELD
The Microflown Acoustic Camera employs advanced algorithms for precise transient noise visualization. Through near-field acoustic holography, it reconstructs the emitted sound field, ensuring a consistent spatial resolution across the entire audible frequency range. Each probe in the array contains a microphone and a 1D particle velocity sensor, capturing essential data for tackling complex acoustic challenges. This array benefits from measuring near the sources, ensuring unparalleled spatial resolution results even for low frequencies.
SOUND SOURCE LOCALIZATION AND QUANTIFICATION OF ACOUSTIC EMISSION
The near-field acoustic camera effectively analyzes and localizes complex sound sources. Thanks to the physical properties of particle velocity, our systems are robust against high levels of background noise. Therefore, we can derive accurate sound intensity and sound power results, even in testing environments with a high sound pressure to sound intensity ratio (P/I index). This distinctive property positions our system as an outstanding engineering resource for troubleshooting, benchmarking, or quality assurance of various objects in their target environment.
MULTIPLE ACOUSTIC SENSOR ARRAY CONFIGURATIONS
Our Near-field Acoustic Camera offers several hardware configurations suitable for any challenge. Its versatility ranges from custom setups to our state-of-the-art handheld array solution. The user-friendly grip of the handheld array allows for quick and easy changes in array grids while keeping a single cable connection to the probe pre-amplifier.
