Monaural and binaural spectral cues created by the external ears of the pallid bat

摘要: The acoustic properties of external ears transform the spectra incident sound in a location-dependent manner, and provide monaural binaural spectral information used 2-dimensional localization. Human studies suggest that differences, peaks notches transfer functions, may all spatial information. This study examined pallid bat ear to determine directionality, interaural intensity as well gain. is gleaning uses passive localization find prey, echolocation for general orientation. It capable very accurate localization, primary focus this was cues might support acuity. Results show create maxima minima vary systematically with azimuth elevation. resemble those reported humans cats, similar are across taxa. also robust differences both These basis 1° angular resolution apparent it bat's performance.
