Question

Play the spectrogram at normal speed and slowed down. How many calls did the bats make?

Answer 1

Bat echolocation calls vary in their dominant frequency approximately between 11 kHz (e.g. Euderma maculatum; Fullard & Dawson 1997) and 212 kHz (Cloeotis percivali; Fenton & Bell 1981). Most insectivorous bats call with dominant frequencies between 20 kHz and 60 kH
