Acoustic Camera AC100

Quickly and effectively locate and analyse sound sources


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 Acoustic Camera AC100 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 for Acoustic Camera - AC100 are:

  • Localization and separation of sound sources to reduce noise emitted by vehicles, machinery, household appliances and electric tools
  • Source analysis for acoustic design of wind tunnel models, complex vibrating structures, creaking or rattling structures
  • Long-term monitoring of machines and plant
  • Acoustic vehicle tests (inside and outside
  • Quality assurance
  • Predictive machine maintenanc
  • Acoustic optimization of product

The handheld acoustic camera AC100 * Compact * mobile * robust * low-cost *

Due to its state-of-the-art microphones in MEMS technology with integrated AD converters and 51.2 kHz sampling rate, together with an integrated measurement data processing electronics in the latest DSP technology, the AC100 is now affordable for wide range of users. The complete integration in the array, with only one USB interface for data and power supply, allows for convenient mobile use with any Windows PC.

The AC100 is a compact and very easy-to-use acoustic camera for standalone applications. Because of its high performance, simple operation and fair price, the AC100 is suitable for a wide range of applications in research and production.

The AC100 is supplied either as pure hardware + Windows driver for custom development or bundled with the BeamformX application software from OptiNav.

AC100 BeamformX software

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.
