Abstract
Headphone equalization is necessary for accurate binaural reproduction
over headphones, but so far no metrics have been
adopted for evaluating human perception of spectral coloration in
post-equalization headphone transfer functions (HpTFs). A metric
for peak error is proposed that represents the average HpTF error
from narrow peaks per third octave band. In addition, a new metric
for broadband error is defined by subtracting the average error
from narrow peaks and notches from that of an auditory filter bank
model. Used together, the peak error and broadband error terms
are shown to represent the critical information necessary for transparent
headphone reproduction.
