WebCetacean Dynamic Range It is well established that Odontoceti echolocate for both short and long range navigation (Norris 1964). The sensitivity of a cetacean to its echolocation signal can be illustrated by the construction of a bioacoustic dynamic range function; the difference between the cetacean’s emission and hearing thresholds.
