Differences in auditory perception between species are influenced by phylogenetic origin and the perceptual challenges imposed by the natural environment, e.g. detecting prey- or predator-generated sounds and communication signals. Bats are well suited for comparative studies on auditory perception since they predominantly rely on echolocation to perceive the world, while their social calls and most environmental sounds have low frequencies. We tested if hearing sensitivity and stimulus level coding in bats differ between high and...
