11. AcoustiCam

Quickly and effectively locate and analyse sound sources

More details

Especially the sound analysis of complex objects often reveals the problem that conventional measurements using a single or just a couple of microphones only deliver insufficient results with respect to the tracking of sound sources. The technique used with AcoustiCam provides an excellent solution. Simultaneous measurements using a large number of microphones allow the quick and precise location and separation of sound sources.


Typical applications

• Locating stationary and transient sound sources

• Long-term monitoring of machines and plant

• Acoustic vehicle tests (inside and outside)

• Quality assurance

• Predictive machine maintenance

• Acoustic optimization of products


Software for the AC100


The AC100 is supplied either as pure hardware + Windows driver for custom development or bundled with the BeamformX application software from OptiNav. BeamformX uses an advanced new evaluation algorithm, the Robust Functional Beamforming. Compared to conventional beamforming methods, Robust Functional Beamforming works faster, has a higher dynamic range and can resolve more details spatially and temporally. Robust Functional Beamforming has been developed by Robert P. Dougherty, OptiNav Inc USA. The stored raw data can also be used in postprocessing with the SAMURAI software from SINUS Messtechnik.


Handheld and conventional acoustic camera with various microphone arrays

We offer a number of different array geometries with detachable 1/4“ ICP microphones optimized for various applications:

• Single circle with 32 microphones (500 Hz to 20 kHz)

• Double circle with 32 microphones (500 Hz to 20 kHz)

• Inline array with 32 microphones for preemptive measurements

• foldable star array with 30 microphones (200 Hz to 20 kHz)

• detachable star array with 30 microphones (1 kHz bsi 20 kHz) Each set of 16 microphone signals is connected to the inputs of the Tornado system securely and quickly by means of highly flexible multi-core cables with MDR connectors. This solution also allows use with customer-specific arrays. Various interfaces are available for the programming of Tornado by the user:

    • SINUS MATLAB Toolbox (compileable)

    • LabView Library

    • API for individual programming with C++ or Python

The main advantage of conventional arrays with Tornado is the universal use of the measuring hardware with the detachable microphones (SMB connectors). The same hardware can also be used for sound power measurement according to the envelope area method or for a simulated Indoor Pass-By
