Displacement casued by ultrasound transducer

Hi,

I'm conducting ultrasound experiments on rock samples. In order
to numerically model the wave propagation I need to know the actual particle displacements caused by the ultrasound waves. For example,
does a negative or a positive voltage pulse correspond to a
compressive or a tensile wave pulse? I also would need to know
what displacement amplitudes the ultrasound waves have - some way
to calibrate the displacement in micrometer with the voltage
amplitude measured. Anyone some ideas on this?

Best Regards,
Martin Moellhoff
