Pinniped Hearing in Complex Acoustic Environments

Abstract

Pinnipeds (seals, sea lions, and walruses) are amphibious marine mammals that are susceptible to coastal anthropogenic noise. The long-term goals of this effort are to improve understanding of (1) the sound detection capabilities of several pinniped species, and (2) the effects of noise exposure on the sound detection capabilities of these species. The laboratory and field studies associated with this research will reveal certain aspects of how amphibious mammals receive, perceive, and recognize acoustic information in background noise and will contribute broadly to current knowledge of marine mammal bioacoustics.
