Inter-pulse interval (IPI) in the large flight room. A The experiment consisted of four stages, moving between two environments: a large flight room (grey) and a smaller cluttered flight chamber (yellow). B The large flight room was 5.5 × 4.5 × 2.5 m3. The landing platform was located in the center of the room with an ultrasonic microphone attached to it and directed towards the bat. Twenty tracking cameras recorded the flight path of the bat. C The IPI measured during the approach phase of the echolocation in the last 150 cm before landing for two time points in the experiment (mean ± SE; n = 5): before the cluttered chamber experiment (stage 1), and immediately after the cluttered chamber (stage 3). SE’s are depicted, but are very small. Data was normalized for all individual bats by dividing each bat’s data by its maximum value (the maximum across all trials)
