A model and experimental approach to the middle ear transfer function related to hearing in the humpback whale (Megaptera novaeangliae)
At present, there are no direct measures of hearing for any baleen whale (Mysticeti). The most viable alternative to in vivo approaches to simulate the audiogram is through modeling outer, middle, and inner ear functions based on the anatomy and material properties of each component.
