Testing technology for the measurement of interfering noises

Schwingerregung per Shaker

Vibration excitation

The mobile high-power shaker [HPS] for components is used to excite individual components and assemblies.

The mobile high-performance shaker for vehicle excitation can be used to excite complete vehicles while stationary and to simulate driving profiles that correspond exactly to those of real road driving.


Transient noise

The OCIAN method enables the objective evaluation of transient background noise, which can be heard from a stationary background noise for example the driving noise in a car.

The evaluation is carried out by detecting and classifying squeaking, rattling and creaking noises in relation to the instantaneous level of background noise.


Vibro acoustics

ZoundLab is a PC-based measurement and test system for recording, analyzing and objectively evaluating vibration and sound.

It can be used stationary with lab test stands or as inline quality test stands as well as for mobile measurements in the field or vehicle.
