In the very near field the acoustic particle velocity and the structural velocity are linear related and that the underestimation of the structural velocity measured by the acoustic particle velocity is less than 3dB.
At the same time it is also possible to determine the sound intensity and with that the radiated sound power.
It is therefore possible to determine the structural modes and at the same time find out how much sound these these modes radiate to the far field.
