    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.
