Relation between mechanical microhardness and impedance ...Jan 01, 2004 · The relation between impedance and micro hardness is important in the non-ferromagnetic case. We can use the impedance measurement to determine the micro hardness of the studied samples. The same observation can be made for the ferromagnetic material where the hardness and the impedance have the same behavior.

What Speaker Impedance Means and Why It Matters

Nov 13, 2020 · The impedance of a speaker changes as the sound goes up and down in pitch (or frequency). For example, at 41 hertz (the lowest note on a standard bass guitar), the impedance of a speaker might be 10 ohms.
