Sound Localization and Visualization

When sound is annoying, its name is noise. When noise is the problem for any reason like high and dangerous levels for the human ear, malfunction of and failures in machines, lacking acoustic comfort or sound quality, … we measure, visualize and localize the sources and finally analyze them.

Our algorithmic tools are three localization techniques: beamforming, intensity and holography. The Acoustic Camera applies all three techniques in conjuction with different microphone arrays.

The measurement results show the main and secondary sound sources in acoustic maps as well as the related frequency range. This useful data is provided as photo, video, or 3D model with a spectral-colors overlay.

Remember when you analyse and reduce noise, the first step is to localize it.

Use the best tool, use the Acoustic Camera.

The Acoustic Camera

The Acoustic Camera was the first commercially viable system using beamforming to visually localize acoustic emissions. Brought to the market in 2001 as a pioneer technique, the Acoustic Camera has become a metaphor over the years for beamforming systems in general. The tool is now used in a variety of industries and has a growing customer base worldwide.

Our brochure "Listening with your eyes" presents the wide range of application and gives an overview of the system components. 

We offer different Acoustic Cameras for different applications, the AC Pro system and all-in-one sound cameras.

The original Acoustic Camera is a one-stop system developed fully in-house. Data acquisition, microphone arrays and software come fully integrated. That is only one of the many reasons why we outperfom any solution on the market.

Mechanical vibrations occur throughout nature and in our daily lives and affect the safety, durability and comfort of structures. Therefore, it is important to detect and analyze them easily and quickly in the development and prototyping process but also for maintenance of existing structures. Use our new vibration testing products to efficiently excite, measure, analyze and simulate vibrations without any expert knowledge:

  • our automatic modal hammer WaveHitMAX, which enables high-precision impulse excitation,
  • our vibration analysis software WaveCam, which allows uncomplicated and fast vibration analysis based on camera measurements, and
  • our simulation software WaveSim, which offers state-of-the-art finite element methods adapted to these results of the WaveCam.

Ensuring and maintaining a specified product quality during production is of elementary importance for the manufacturing company. Errors in production and the resulting rejects or, in the worst case, product recalls must be avoided at all costs. With our solutions, this risk can be significantly minimized through production-accompanying and non-destructive quality assurance with vibration and acoustic measurements. In order to additionally reduce the required expert knowledge for quality assurance, we use artificial intelligence methods. 

AI-Powered Testing System QAIros

Process-integrated quality assurance (QA) plays a vital role in manufacturing, especially in critical industries like automotive and medical technology, where the Zero Defects (ZD) concept is often mandatory. Our quality testing system, QAIros, offers a solution with the highest reliability for defect detection.
