Trains have irrevocably established themselves in our travel behavior as a fast and comfortable means of transport. ICEs, TGVs and Shinkansen bullet trains connect cities on high-speed rail routes. Even at a speed of 250 km/h,
travelers on these high-speed trains have no problems at all talking to one another, listening to music,
or relaxing in their seats and watching the countryside rush by.

Suburban and underground rail systems carry millions of passengers every day. Reliability and robustness are just as important here as comfort.

Sample-synchronous Interconnection

Its modular design makes PAK a suitable instrument for measuring acoustics and vibrations.
Systems distributed throughout the length of a train are sample-synchronously interconnected.
Sometimes it is the operation deflection shape that is of interest; at other times the modal analysis is the
right tool. Or it comes down to the interior acoustics – everything can be analyzed and documented with a PAK system!
