| Abstract(in English) | In this paper, we discuss the DOA (Direction Of Arrival) estimation method using sub-band peak hold processing, which avoid the undesirable effect of reflected sound in a room. In this method, the reflected sound is reduced by peak hold processing, which maintains the amplitude of the direct sound and masks subsequent reflected sound at each sub-band. The sub-band peak hold processing is applied with the cross-correlation function method, which is a typical DOA estimation method. To evaluate the effectiveness of the proposed method, a DOA estimation experiment was conducted under actual environmental conditions. As a result, the robustness of this method for reflected sound was shown to be higher than those of the conventional CC (Cross Correlation) and PHAT (PHAse Transform) methods. |
