Reactance is the energy storage and discharge from capacitors and inductors, so no power is converted to another form. Reactive loads result in ‘reactive’ power. Impedance is the overall opposition to current flow in an AC circuit, resulting in the ‘apparent’ power loss. Impedance is the Pythagorean sum of resistance and reactance.

Acoustic impedance and specific acoustic impedance are measures of the opposition that a system presents to the acoustic flow resulting from an acoustic pressure applied to the system. The SI unit of acoustic impedance is the pascal-second per cubic metre (Pa·s/m 3), or in the MKS system the rayl per square metre (rayl/m 2), while that of specific …
