Quality control and localization based on variations in sound emissions

The acoustic camera allows the identification of faults and defects.

Many of us have already experienced the following situation: The car engine is running, but something seems to be wrong. The soundscape is different. Even before any warning light on the dashboard comes up, an experienced driver can hear that something is wrong with the car. The same is true for many industrial applications: Numerous faults can be detected just from variations in the sound emission.

In quality control, experienced workers can often identify faulty products just from their abnormal sound.

The acoustic camera can find faults resulting in variations in the soundscape, without depending on the disposition of quality assurance (QA) staff. Two acoustic images can be placed side by side in the software to perform a simple comparison of nominal and actual values. The same value range is applied to both images with a click of a mouse button. Any variations become obvious, and the visual presentation also reveals where exactly the fault is located.
