Hearing in 3D

The sonar system of bats exploits spatial information in a way similar to our sense of sight, despite the different anatomy of eyes and ears. In a new study, scientists at the Max Planck Institute for Ornithology in Seewiesen and the Ludwig Maximilians University Munich have now shown that echoes contain information that allows bats to distinguish differently structured surfaces. On a turbulent water surface for example, a fidgety prey item acoustically stands out even against the clutter of the background waves.
