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

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

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

It is possible, however, using psychophysical techniques first developed for human measurements, to characteriz
