Bats Could Learn Three-Dimensional Echolocation Using Echoacoustic Flow
Echolocating bats can find prey and avoid obstacles in three dimensions using sound alone. They infer the direction of an echo from the way the emitter, the head and the outer ears filter sound, together described by the echolocation-related transfer functon(ERTF). This filter differs between species and is likely to change as the ears grow, so it has to be calibrated by experience. Barn owls and…
