Fig. 2. Diagram of experimental set-up. Bats were trained to sit on the Y-shaped
platform and search for the target located 30 cm away, responding by moving
forward onto the corresponding platform arm for food reward. CF jamming sounds
were presented from the loudspeaker located 1.5 m away, and the bat's sonar
sounds were recorded by microphones located 1.5 m away and separated by
30°.
