In some applications, it is of interest to localize more sources than number of sensors. For a class of nonstationary wideband sources that exhibit onset-offset-like behavior, we develop a statistical test to choose desirable time-frequency bins where we apply the MUSIC or minimum variance estimators. Finally, we fuse the localization results across those time-frequency bins. Experimental results with a pair of real hearing-aid microphones indicate successful localization of four speech sources.
