This paper discusses the influences of reflected sound and background noise on DOA (Direction of Arrival) estimation using two microphones. The study is performed based on mirror images simulation. Main results are 1) the influence of reflected sound is larger than that of the noise by about 8 dB, 2) PHAT and SCOT methods achieve better performance than CC method. This is because PHAT and SCOT methods sharpen their cross-correlation peaks and discriminate the correct peak from phantom peaks caused by reflected sounds. |
