Hearing in American leaf-nosed bats. IV: The Common vampire bat, Desmodus rotundus

► We trained Common vampire bats, Desmodus rotundus, to respond whenever they heard a tone. ► Thresholds were obtained at 30 frequencies from 250 Hz to 116 kHz ► At a sound pressure level of 60 dB, D. rotundus can hear from 716 Hz to 113 kHz ► D. rotundus is more sensitive to low frequencies than any other bat tested behaviorally but does not hear low frequencies as well as most mammals.
