Dear collegues, I would like to draw attention to my recently published paper:
V. A. Ryabov, "Acoustic Signals and Echolocation System of the Dolphin" If you would like a pdf copy of the paper, please send an e-mail to: [email protected] Abstract. Two-channel recording of acoustic signals from two quasi-stationary dolphins has previously suggested that the dolphin echolocation system is more complex than discussed earlier, and includes at least four sonars. In the present work, two-channel recording of signals, analysis and interpretation of their functions were continued in terms of physical acoustics, signal theory and echolocation. The results indicate that the echolocation system of dolphins involves four organs to produce probing signals of five different types, which implies different mechanisms of their processing by the dolphin hearing; its operation corresponds to as many as six varieties of sonar systems. The results are of importance for studying the echolocation system of Odontoceti and for improving sonars and radars.
