Link to Ketten Laboratory Research - Marine Mammal Hearing

Ketten lab research studies are directed at understanding how the ears of marine animals, particularly whales and dolphins, are able to hear and use underwater sounds. Biomedical (CT and MRI) micro-imaging techniques are used to study auditory systems from a wide range of species and to produce mathematical and three-dimensional computer models of marine ears. The models allow us to estimate hearing abilities for rare and endangered species, like blue whales (Balaenoptera musculus), that cannot be tested by normal methods.
