Anthropogenic noise may be a major source of habitat degradation for cetaceans. To assess and mitigate the effects of noise pollution on marine mammals, we need information on how and what they hear. Although hearing in odontocetes, or toothed whales, is well studied, few data are available for mysticetes, or baleen whales. Behavioural and electrophysiological hearing tests are presently impractical for mysticetes, but biomechanical, structural modelling provides hearing estimates based on… Expand
Beaked and Baleen Whale Hearing: Modeling Responses to Underwater Noise
Abstract : Ultimately this research is to provide proof of concept for using modeling techniques to provide reliable hearing estimates for species thought to be most liable to impacts from oceanicExpand
Comparative anatomy of the bony labyrinth of extant and extinct porpoises (Cetacea: Phocoenidae)
TLDR
Digital endocasts of the inner ear labyrinths of representative species of extinct and extant porpoises of a clade of some of the smallest odontocete cetaceans are explored, demonstrating a good match between those predicted to have coastal preferences and high canal deviation values and a new body length relationships based on correlations with inner ear Labyrinth volume.

Hearing in cetaceans: from natural history to experimental biology.
TLDR
This chapter addresses topics including how sounds are received, what sounds are detected, hearing mechanisms for complex acoustic scenes, recent anatomical and physiological studies, the potential impacts of noise, and mysticete hearing. Expand
Prenatal cranial ossification of the humpback whale (Megaptera novaeangliae)
TLDR
This study uses high‐resolution X‐ray computed tomography to reinvestigate humpback whale fetuses from the Kükenthal collection at the Museum für Naturkunde, Berlin, thus, extending historic descriptions of their skeletogenesis and providing for the first time sequences of cranial ossification for this species.

A sense of scale: Foraging cetaceans' use of scale‐dependent multimodal sensory systems
TLDR
It is postulate that cetaceans utilize a scale-dependent, multimodal sensory system to assess and increase prey encounters, and builds two “scale-of-senses” schematics for the general groups of dolphins and baleen whales. Expand

TLDR
The cochlear frequency map derived from these single-neuron labeling experiments is compared to maps derived by a number of different physiological and psychophysical techniques, and the significance of the similarities and differences is discussed. Expand
