Acoustics Today A Publication of the Acoustical Society of America Volume 7, Issue 4 October 2011 Cover: Playback experiments (in which recorded vocalizations are broadcast in the field to freely-behaving animals and responses are recorded) have shown that the extent of elephants’ defensive responses (bunching together, retreating) to the voices of elephants from the other family groups encountered within their range can be predicted by the frequency with which those animals are encountered.

Owren Basic biological forces affecting vocalization in other species have also shaped the human voice. 35 Phonetics of Endangered Languages—D. H. Whalen, Christian T. DiCanio, and Patricia A.
