..., narrowing depending on target distance. In this study, we further tested this beam focusing hypothesis in a false killer whale. Using three linear arrays of hydrophones, we recorded the same emitted click at 2, 4 and 7 m distance and calculated the beamwidth, intensity, center frequency and bandwidth as...

...Vladimir V. Popov; Alexander Ya. Supin; Viatcheslav V. Rozhnov; Dmitry I. Nechaev; Evgenia V. Sysueva The influence of fatiguing sound level and duration on post-exposure temporary threshold shift (TTS) was investigated in two beluga whales ( Delphinapterus leucas ). The fatiguing sound was half...

...Arnoldus Schytte Blix; Lars Walløe; Edward B. Messelt SUMMARY Whales are unique in that the supply of blood to the brain is not by the internal carotid arteries, but by way of thoracic and intra-vertebral arterial retia. We found in the harbor porpoise ( Phocoena phocoena ) that these retia split...

...Paul E. Nachtigall; Alexander Ya. Supin SUMMARY We investigated the possibility of conditioned dampening of whale hearing thresholds when a loud sound is preceded by a warning sound. The loud sound was a tone of 20 kHz, 170 dB re. 1 μPa, 5 s. Hearing sensitivity was measured using pip-train test...

...Alexander J. Werth SUMMARY Despite its vital function in a highly dynamic environment, baleen is typically assumed to be a static material. Its biomechanical and material properties have not previously been explored. Thus I tested sections of baleen from bowhead whales, Balaena mysticetus , and...
