[Bioacoustic characteristics of echolocation system of the long-eared European bat Barbastella barbastella]
Abstract:
Experimental data on the echolocation system parameters of Barbastella barbastella are reported. They include the parameters of orientation pulses, auditory frequency-threshold curves and characteristics of reception directionality of the external ear. It is demonstrated that the hearing system of this bat species has two hypersensitivity regions, which are tuned to the frequency components of the location call. Spatial diagrams of reception directionality have a complicated frequency-dependent configuration. Using the data obtained the authors consider possible mechanism of target direction finding.

Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case, then the...
