Apparatus for rectifying resonance in the outer-ear canals and method of rectifying |
摘要 |
According to one embodiment, an apparatus for cancelling resonance in an outer-ear canal, comprises an outer-ear canal model includes attenuator modules representing reflection coefficients of an earphone or headphone and an eardrum, and a delay module having a delay time corresponding to a distance between the earphone or headphone and the eardrum, an inverse-filter forming unit configured to form an inverse filter of the outer-ear canal model, and a convolution module configured to perform convolution on an impulse response from the inverse filter and a sound-source signal. |
