Pitch perception is critical for recognizing speech, music and animal vocalizations, but its neurobiological basis remains unsettled, in part because of divergent results from different species. We used a combination of behavioural measurements and cochlear modelling to investigate whether species-specific differences exist in the cues used to perceive pitch and whether these can be accounted for by differences in the auditory periphery. Ferrets performed a pitch discrimination task well whenever temporal envelope cues were robust, but not when resolved harmonics only were available. By contrast, human listeners exhibited the opposite pattern of results on an analogous task, consistent with previous studies. Simulated cochlear responses in the two species suggest that the relative salience of the two types of pitch cues can be attributed to differences in cochlear filter bandwidths. Cross-species variation in pitch perception may therefore reflect the constraints of estimating a sound’s fundamental frequency given species-specific cochlear tuning.
