Mechanical surface impedance

There are various interpretations of MechanicalSurfaceImpedance: Pressure/Velocity - https://apps.dtic.mil/sti/pdfs/ADA315595.pdf, Force / Speed - https://www.wikidata.org/wiki/Q6421317, and (Pressure / Velocity)**0.5 - https://www.sciencedirect.com/topics/engineering/mechanical-impedance. We are seeking a resolution to these differences.

Mechanical surface impedance at a surface, is the complex quotient of the total force on the surface by the component of the average sound particle velocity at the surface in the direction of the force

$Z_m = Z_a A^2$, where $A$ is the area of the surface considered and $Z_a$ is the acoustic impedance.
