Abstract

A system for calibrating a headphone fixture includes one or more headphones disposed at the headphone fixture and a controller configured to generate a test electroacoustic performance signal based on an audio signal obtained from the one or more headphones, obtain a reference electroacoustic performance signal associated with one or more test subjects and the one or more headphones, determine an electroacoustic performance difference signal based on the test electroacoustic performance signal and the reference electroacoustic performance signal, define a compensation filter based on the electroacoustic performance difference signal, and determine whether the one or more headphones satisfy a performance criteria based on one or more additional test electroacoustic performance signals and the compensation filter.
