Ring Arrays detail

Microphone Arrays

For the arrangement of the microphones we offer different arrays constructions for different applications. In addition to our wide range of standard shapes and sizes, we can build an individual array depending on the requirement of the user.

Arrays for 2D measurements

Depending on their size, Ring Arrays provide 32, 48 or 72 microphone channels. This type of array is suitable for various 2D beamforming applications.The Star Array is the perfect choice for far field measurements using the beamforming method. The Fibonacci Array can be used for near field and far field measurements, using the holography or beamforming method. For wind tunnel applications the Evo Array is specialized.

All arrays are a custom made carbon fiber construction to assure light weight and stability. Thez are therefore easily transportable and assures a constant microphone position over a long time.

Arrays for 3D measurements

For 3D measurements, the microphone array receives signals from all directions. The beamforming results are mapped on scanned 3D point clouds or 3D CAD models of the measured object. Especially developed for interior measurements, the Sphere Arrays with 48 or 120 microphone channels are suitable for different scenarios.

Arrays for near field measurements

As hand-held devices, Paddle Arrays are the ultimate low frequency measurement tool. As a double-layer channel system, it was developed for near field measurements and low frequencies using the intensity method. These portable Paddle Arrays allow for real-time acoustical measurements. The measurement of acoustic pressure signals can be conducted while particle velocity/acoustic intensity on the measurement plane is calculated and mapped simultaneously.

The Fibonacci Array represents a new array family allowing near field and far field measurements with the same hardware, using the holography or beamforming method.

Latest Developments

Fibonacci 120 AC Pro - Evo AC Pro - 3-in-1 AC Pro - Array Design Kit - Star 48 AC Pro

State-of-the-art technology: Recently developed arrays for individual customer requests provide new measurement possibilities. The Fibonacci Array is the first array, which can be used for the beamforming as well as the holography method. With the Evo AC Pro we can now present a microphone array, perfectly suited for wind tunnel applications.

Customizable arrays like the 3-in-1 Array and the Array Design Kit enable the user to adjust one array to different measurement scenarios.
