摘要
Headphone equalization can help to deliver high perceptual sound quality. The headphone-to-eardrum transfer function (HETF) equalization can be used to control magnitude and phase responses of headphones. Magnitude equalization is still elusive on how to set a preferred target response while phase equalization is an important but overlooked method. Here the targets of magnitude equalization and phase equalization on headphone reproduction were evaluated through objective and subjective experiments. The objective evaluation shows that the linearity of phase response is important for the decay speed of the corresponding transient response. The subjective experiments show that the target of a linear phase response, but not a flat magnitude response, is able to significantly improve headphone reproduction quality in sound clarity.
