AN ACOUSTIC IMAGING SYSTEM WITH UNMATCHED SPATIAL RESOLUTION
Our testing solution provides engineers with a powerful tool for acoustic imaging and noise source identification, achieving exceptional spatial resolution within the full acoustic bandwidth. It is designed specifically to visualize time-stationary sound fields accurately, making it an ideal choice for various engineering needs such as troubleshooting, soundproofing, and product benchmarking. With the utilization of cutting-edge PU probe sensing technology, you can efficiently conduct measurement campaigns and obtain precise acoustic imaging results. Gain valuable insights into the precise location of sound sources across low, mid, and high frequencies.
Visualize sound propagation and source interactions in a three-dimensional rendering environment, offering unparalleled clarity in identifying and solving noise issues. This single-probe solution allows you to visualize what you hear, simplifying any complex acoustic problem.
FEATURES
3D visualization of:- Sound intensity vectors- Particle velocity vectors- Sound pressure distribution
Broadband Solution | 20Hz – 10kHz
Fast Method: short setup, measure, and process time
Applicable in (real) operating environments
Automatic 3D tracking of the sensor position
2D visualization available for all angles of the 3D model
The Near-Field Acoustic Camera excels in the localization and real-time analysis of non-stationary sound sources, including buzz, squeak, and rattle noises. This stands apart from traditional techniques by employing an array of PU sound intensity probes that captures more than just sound pressure. Consequently, the Near-Field Acoustic Camera delivers precise acoustic results 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.
FEATURES
Frequency range 20Hz – 10kHz
Large dynamic range | up to 45 dB
High, frequency independent, spatial resolution
Applicable in (real) operating environments
Visualization of transient & non stationary sound fields
Microflown Technologies offers a complete solution to measure the acoustic properties of materials with its In-situ absorption setup. This method is a true alternative for the well known Kundt’s method or reverberant room method.
With a small, handheld impedance gun the acoustic absorption, reflection or impedance can be measured in just a few minutes, broad banded, under normal and oblique angles. With a sound source at 23cm from the probe the noise is generated towards the sample. The sound pressure and acoustic particle velocity are measured right on the surface of the material.
FEATURES
Frequency range 300Hz – 10kHz
In-situ method
Normal & oblique angles of incidence
Flat & curved surfaces
Homogeneous & inhomogeneous materials
Fixed and moving surfaces
Can be used for:

Human ears only hear sound pressure, with Scan & Listen particle velocity is now also made audible!
Human ears are like traditional microphones sensitive to scalar value (omnidirectional sound pressure), the Microflown however is sensitive for vector value (directional acoustic particle velocity). A combination of a Microflown with the Scan & Listen device are making our ears capable of hearing particle velocity! Listen to what nobody heard before. Listen to noise source in situations with background noise and reflections. Locating sound sources in practical environments can be difficult. Especially in situations with non-stationary sources like squeak & rattle. Just listening to particle velocity can give you better results than extensive, detailed FFT analysis!
Scan & Listen method performs quick scans instead of time consuming series of measurements. It is an intuitive method of sound source localization. Also acoustic leakages can be detected fast and accurately with the system. Quick, fast and mobile are keywords for Scan & Listen, as well as it is practical, simple and handheld. The system also has the option to record simultaneously while listening. Scan & Listen set- up contains a background noise reducing headphone (passive -40dB ), so the signal of particle velocity is even clearer in your ears.
FEATURES
Direct listening to particle velocity
Low susceptibility to background noise and reflections
Easy finding of sources; also non stationary transients such as ”squeak & rattle”
Easy finding of modes / vibration pattern determination
