The Role of Cranial Structures in Odontocete Sonar Signal Emission

  • Gustavo Alcuri
Part of the NATO Advanced Study Institutes Series book series (volume 28)


Two independent hypotheses attempt to explain the sonar signal transmission mecanism on its path towards the outside environment:
  1. 1)

    focalization through reflection on the concave surface of the anterior cranial region,

  2. 2)

    transmission through the premaxilla.
