Measuring the Effective Impedance and Sensitivity of Headphones

Measuring the Effective Impedance and Sensitivity of Headphones

This article has two parts. Part I describes a way to determine the effective average impedance of a pair of mono headphones or a speaker using a device called a FILVORA. Part II shows how to compare the sensitivity of two speakers or two mono headphones using a dual FILVORA, even if the headphones differ greatly in impedance.
