It is shown that, for three- and two-microphone systems, two and four samples of the Interaural Time Difference (ITD) measurements are required respectively. In a one-microphone system, five samples of the Interaural Intensity Difference (IID) measurement should be used instead. These investigations are important because if one microphone fails, the remaining system can still function to locate the sound source without significant impact on the localization system. In addition, our investigation also shows that a 3-microphone system can estimate the azimuth and elevation simultaneously, which usually requires 4 microphones in the literature. Simulation and experimental results are presented to illustrate the performance of a three-microphone system. Results show that the system can locate the sound source with satisfactory accuracy. <\/jats:p>","DOI":"10.1142\/s0219878905000386","type":"journal-article","created":{"date-parts":[[2005,5,26]],"date-time":"2005-05-26T06:38:17Z","timestamp":1117089497000},"page":"1-22","source":"Crossref","is-referenced-by-count":1,"title":["ROBUST SOUND LOCALIZATION USING SMALL NUMBER OF MICROPHONES"],"prefix":"10.1142","volume":"02","author":[{"given":"SHUZHI SAM","family":"GE","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, National University of Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"AI POH","family":"LOH","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, National University of Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FENG","family":"GUAN","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, National University of Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1109\/TSMCB.2002.804369"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1109\/89.554268"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1006\/csla.1996.0024"},{"key":"rf5","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-662-04619-7","volume-title":"Microphone Arrays \u2014 Signal Processing Techniques and Applications","author":"Brandstein M.","year":"2001"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1109\/89.486067"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1109\/78.301830"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2002.800420"},{"key":"rf11","doi-asserted-by":"crossref","DOI":"10.7551\/mitpress\/4808.001.0001","volume-title":"Music, Cognition, and Computerized Sound \u2014 An Introduction to Psychoacoustics","author":"Cook P.","year":"1999"},{"key":"rf12","first-page":"15","volume":"19","author":"Cui Y.
