Headphone equalization is essential to binaural listening. Equalization algorithms have previously been optimized by hand using heuristics and a small set of measurements from a single institution. The PHOnA Project allows us to compare different equalizations across data from many laboratories. This paper develops a set of objective metrics for the psychoacoustic phenomena that cause audible coloration during headphone listening. This will allow a better understanding of how to create a transparent reproduction channel for 3D audio listening via headphones.
