Noise and vibration measurement

We offer noise and vibration measurement and analysis of machinery and equipment. The employed measurement instruments provide multichannel measurements of dynamic quantities and their evaluation in the time and frequency domains in real time or during signal post-processing.
Measurements of other physical quantities can be added to the noise and vibrations measurement. Special acoustic laboratories are available for precise measurements.
