Key Points

To assess how auditory critical bandwidth influences the ability of pinnipeds to separate acoustic signals from ambient noise.
Evaluated critical bandwidth measurements across pinniped species to characterize auditory filter width.
Assessed behavioral and psychoacoustic responses to sound signals embedded in varying levels of background noise.
Critical bandwidth metrics demonstrated measurable species-level differences in noise-filtering efficiency among pinnipeds.
Auditory filter tuning determined the extent to which background acoustic noise masks essential underwater signals.
