| Abstract(in English) | The method of estimation of direction of arrival (DOA) from an acoustic source in a reverberant environment is studied using 3-element sphere-baffled microphone (3E-SBM), i. e. 3 microphones are embedded in the horizontal great circle of the sphere. This method is implemented in a system with 3E-SBM and the diffractive information directory (DID) of the SBM in a free sound field, and is expected to well work in longer reverberant environment. Computer experiments are conducted for a 2-D room model to verify the validity of the proposed method: items examined are the accuracy of estimated DOAs, the robustness for additive uncorrelated random noises, and the effect of source-SBM distance of the DID to be used in the DOA estimation. |
