title = "Biologically inspired beamforming with small acoustic arrays",
abstract = "Many biological hearing systems perform much better than existing signal processing systems in natural settings. Two biologically inspired adaptive beamformers, one mimicking the mammalian dual-delay-line localization system, show SNR gains in challenging cocktail-party scenes substantially exceeding those of conventional adaptive beamformers. A {"}zero-aperture{"} acoustic vector sensor array inspired by the parasitoid fly Ormia ochracea and accompanying algorithms show even better performance in source recovery than the binaural beamformers, as well as the ability to localize multiple nonstationary sources to within two degrees. New experimental studies of the performance of the biologically inspired beamformers in reverberation show substantial reduction in performance in reverberant conditions that hardly affect human performance, thus indicating that the biologically inspired algorithms are still incomplete.",
