Christopher J. Struck (CJS Labs) discusses all options available for headphone testing and calibration. The article discusses what should be included in a complete headphone test system, considerations on electrical impedance, considerations on repeatability of the results, free and diffuse field corrected responses, left-right tracking, and the use of two-tone distortion measurements.
