Whale Hearing Models

Abstract

The specific objective of this project was to develop biophysically based models of the inner and middle ear of a range of marine mammals to allow us to estimate audiograms from anatomical and mechanical measurements. This project was designed to provide modular data to be integrated with the methodologies and partnership projects developed under the ONR Effect of Sound in the Marine Environment (ESME) Program. The effort involved an integration of anatomical and physiological data. Anatomical analyses (WHOI/D.R. Ketten) characterized head, middle, and inner ear structures of represenative odontocete species Physiological Modeling (BU/ David Mountain) implemented auditory response models using the anatomical data. This is the rrequisite first step towards developing species- specific TTS models.
