Based on studies of the CAS Institute of Acoustics, the „design“ of the coupled ears of a nocturnal fly (Ormia ochracea) has helped to develop a miniaturized circuit which detects the source of sounds even though the interaural distance is extremely small. In the fly, the ears are coupled by a flexible cuticular lever which makes both interaural phase difference and intensity difference available for localization.
