Propagation of beluga whale echolocation signals [PDF]
The Journal of the Acoustical Society of America, 1984 The propagation characteristics of high-frequency echolocation signals (peak energies above 100 kHz) of the beluga whale, Delphinapterus leucas were determined by a series of measurements conducted while the animal performed a target-detection task. The whale was trained to station on a “bite-plate” so that its projected beam could be measured in the ...
