Research Abstract |
Spatio-temporal frequency analysis is applied to measured head-related impulse responses(HRIRs), and the method of suppressing a reverberation using spatio-temporal frequency analysis is proposed. From results, the spatio-temporal spectrum of HRIRs concentrated in the triangle region and the spatio-temporal spectrum of diffusive noises appeared outside of HRIR's region. The proposed method can suppress a reverberation.
