Transfer Function

[180263]

I'm measuring the transmission of velocity of vibrations through two points of a vibration path using a sweep signal, two laser vibrometers (one to check input and one to check output) and a 2 ch. FFT analyzer. I obtain a velocity transmissibility in terms of spectrum gain from input to output. Is it possible to use the same transmissibility function to extrapolate the gain in displacement from one point to the other ?
Can I evaluate the energy transmission between this two points ?

Many Thanks

The corresponding transmissibilty magnitudes are theoretically the same for displacement, velocity, and acceleration.
