How is sound conducted to the cochlea in toothed whales? by Zosuls, A., Mountain, D., Ketten, Darlene

“…© 2015 AIP Publishing LLC. Toothed whales (Odontocetes) typically have small occluded ear canals and sea water has a characteristic impedance that is much more similar to the impedance of soft tissues of the head than is the case for the air-tissue interface in terrestrial mammals. …”

Acoustic surveying for beaked whales in the Coral Sea as a mitigation measure for naval exercises by Cato, D., Savage, M., Dunlop, R., Parnum, I., Blewitt, M., Sue, G., Donnelly, D., Cleary, J., McCauley, Robert

“…All toothed whales produce echolocation clicks or pulses with a small number of cycles and most energy at ultrasonic frequencies. …”

How tolerant are harbour porpoises to underwater sound? by Lucke, Klaus, Lepper, P., Blanchet, M., Siebert, U.

“…The documented masked TTS level of the harbour porpoise is considerably lower than levels found in other toothed whale species tested so far, thus supporting the hypothesis of size dependant differences in the tolerance of the auditory system in toothed whales. …”

The Auditory Anatomy of the Minke Whale (Balaenoptera acutorostrata): A Potential Fatty Sound Reception Pathway in a Baleen Whale by Yamato, M., Ketten, Darlene, Arruda, J., Cramer, S., Moore, K.

“…Cetaceans possess highly derived auditory systems adapted for underwater hearing. Odontoceti (toothed whales) are thought to receive sound through specialized fat bodies that contact the tympanoperiotic complex, the bones housing the middle and inner ears. …”

Elastic modulus of cetacean auditory ossicles by Tubelli, A., Zosuls, A., Ketten, Darlene, Mountain, D.

“…In the present study, theelastic moduli of the auditory ossicles (malleus, incus, and stapes) of eightspecies of cetacean, two baleen whales (mysticete) and six toothed whales(odontocete), were measured using nanoindentation. …”

Auditory temporal resolution and evoked responses to pulsed sounds for the Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) by Mooney, T., Li, S., Ketten, Darlene, Wang, K., Wang, D.

“…Among odontocetes (toothed whales, dolphins, and porpoises), it has been suggested that porpoises may have temporal processing abilities which differ from other odontocetes because of their relatively narrow auditory filters and longer duration echolocation signals. …”

Fatty sound reception in minke whales: the lipid composition and potential function of fats associated with mysticete ears by Yamato, M., Koopman, H., Feijoo, G., Ketten, Darlene, Niemeyer, M.

“…Cetaceans possess highly derived auditory systems because a conventional pinna and air-filled ear canal are ineffective at collecting and guiding sound towards the middle ears in an aquatic environment. Odontocetes, or toothed whales, receive sound through specialized “acoustic fats” associated with the mandibles and ears. …”

Underwater Sound Sources and Ambient Noise in Fowlers Bay, South Australia, during the Austral Winter by Ward, Rhianne, McCauley, Robert, Gavrilov, Alexander, Charlton, Claire

“…Sound sources of biological origin include baleen and toothed whales, fish and shrimp. Physical sources of underwater sound include wind- and rain-driven noises, and underwater sounds of anthropogenic origin were primarily from boats and occasionally from an aircraft. …”
