Hearing in Whales and Dolphins: An Overview, A few species even inhabit fresh water lakes and rivers. A list of the 80 species of cetaceans is conveniently presented in a table by Ridgway 1997. Cetaceans vary considerably in size, from the very large blue whale (.), which is the largest living mammal, to the very small harbor porpoise (.) and不可接触 发表于 2025-3-23 18:54:50

In Search of Impulse Sound Sources in Odontocetes,ocete sounds were published in 1949, when Schevill and Lawrence used a Dictaphone machine to record sounds from the white whale, .. These “sea canaries” generated a rich variety of sounds that were reproduced on two phonograph records (Schevill and Lawrence 1950; Schevill and Watkins 1962). The reco躺下残杀 发表于 2025-3-24 03:50:23

The Auditory Central Nervous System of Dolphins,terus, the developing dolphin is exposed to abundant sound from the environment because its mother’s body tissues, including the amniotic fluid that bathes the developing fetus, are well matched to seawater in acoustic impedance.

Electrophysiological Measures of Auditory Processing in Odontocetes,pabilities. As has been abundantly documented in this volume and elsewhere, cetaceans make extensive use of sound in echolocation as well as communication behaviors. The cetaceans exhibit extremely broadband frequency sensitivity with hearing extending from below 100Hz (possibly less than 10Hz in th表示问 发表于 2025-3-24 19:32:39
Psychoacoustic Studies of Dolphin and Whale Hearing,ossible to “get inside a dolphins head” and experience what it must be like to hear sounds over 100kHz and discern fine details of the environment, conspecifics, and prey via echolocation.
