while work has been done to characterize frequency sensitivity across species (which does vary quite a bit, especially in the higher ranges (>20khz)), i haven't seen any work that has been done to explore frequency domain perceptual masking curves in a cross species context.
since some species use their auditory systems for spatial localization, i would guess that the perceptual system would be totally different in those contexts.
