Many of us have already encountered the following situation: the car engine is running, but something seems to be wrong. The soundscape is different. Even before any warning lights on the dashboard pop 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 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 NoiseImage to perform a simple comparison of nominal and actual values. The same value range is applied to both images with the click of a mouse button. Any variations become obvious and the visual presentation also reveals where exactly the fault is located.
