This paper proposed a method for estimating monaural DOA in 3D space in this paper that was based on human perception of temporal modulation. We employed the trends and features previously found on HR-MTF by using the MTF concept as important cues that contained spatial information. We also analyzed speech, which is a natural signal that humans use for DOA, to find important features that could be utilized for the method. We finally evaluated the method by deriving the RMSE for 864 possible positions in 3D space with different HRIRs and signals. The results revealed that the proposed method could adequately estimate the DOA with an overall RMSE of 21.9 degrees. |
