SOUND VISUALIZATION WITH UNMATCHED DYNAMIC RANGE
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.

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.

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.
