For the structure analyzed representing a typical building, higher frequencies decrease and lower along with the height of the building. If we consider the fact, that each of the analyzed sources of vibration is characterized by strictly-defined frequency-amplitude spectrum (dominant excitation frequencies for cars are less than 20 Hz, and for the metro oscillate around 40 Hz) a practical diagnostic 9 conclusion naturally arises: when measuring vibrations caused by the metro, it seems to be redundant mounting gauges at the higher floors. Because the sensors mounted on the lower floor may determine the harmfulness of the measured vibration resulting from such transportation. In the case of car induced vibrations the problem is opposite.
