Dolphins May ‘Talk’ Like Humans


By Katie Scott, Wired UK
A study in which recordings of dolphins made in the 1970s were re-analyzed has revealed that dolphins talk to each other in a manner very similar to human speech, using tissue vibrations.

The study by biologists at Aarhus University in Denmark concentrated on the dolphin’s whistle, which was believed to be produced by the resonance of air in the dolphin’s nasal air cavities. This would have implications for how dolphins communicate at depth — increased air pressure would affect the size of the nasal air cavities and therefore the pitch of the sounds they can make.
