Microphone Arrays
-
One of the most important parts of an Acoustic Camera is the microphone array. It determines the spatial distribution of the acoustic microphones and therefore measurement performance of the whole system. In order to achieve the maximum possible performance in any given application, we offer a wide variety of microphone arrays. No matter if the measurement is beamforming, intensity or holography ... we have the right microphone array. For special applications we can design and build custom made microphone arrays according to the requirements of the application.
