Biophysical models of the middle ear can predict audiograms in part via the middle-ear transfer function. Previous work predicted that the frequency range of best sensitivity for the Minke Whale (Balaenoptera acutorostrata) is near the range of vocalizations for that species. A revised middle ear finite element model incorporates middle ear soft tissues as geometry, including the glove finger, the ear drum homologue familiar from terrestrial mammalian species.

The auditory anatomy of the Minke Whale (<em>Balaenoptera acutorostrata</em>): Insights into potential sound reception pathways in a baleen whale

To date, sound reception paths in mysticetes remain unknown. To understand hearing mechanisms in baleen whales, a thorough examination of their auditory anatomy is required. This study combines classical dissection with biomed1cal imaging techniques such as X-ray, computerized tomography (CT), and magnetic resonance imaging (MRl) to describe the anatomy of the minke whale head with a focus on the ear region. Six individuals have been examined to date.
