Echolocation and Behavior

  • Jean-Claude Lévy
Part of the NATO Advanced Study Institutes Series book series (volume 28)


An echolocating animal can adjust its signal in such a way as to receive a constant frequency for which the ear shows maximum sensitivity and ability to recognize echo characteristics. This is known as an “acoustic fovea”. Is this adjustment the effect of automatic or purposeful behavior? Our assumption is that it is an automatic process involving not the echo but the original signal, which is automatically adjusted to obtain an optimal echo whose characteristics are therefore determined and known in advance.
