PRESS RELEASE: Deciphering Dolphin Language with Picture Words
In an important breakthrough in deciphering dolphin language, researchers in Great Britain and the United States have imaged the first high definition imprints that dolphin sounds make in water.
The key to this technique is the CymaScope, a new instrument that reveals detailed structures within sounds, allowing their architecture to be studied pictorially. Using high definition audio recordings of dolphins, the research team, headed by English acoustics engineer, John Stuart Reid and Florida-based dolphin researcher, Jack Kassewitz, has been able to image, for the first time, the imprint that a dolphin sound makes in water. The resulting "CymaGlyphs," as they have been named, are reproducible patterns that are expected to form the basis of a lexicon of dolphin language, each pattern representing a dolphin “picture word.”
Certain sounds made by dolphins have long been suspected to represent language but the complexity of the sounds has made their analysis difficult. Previous techniques, using the spectrograph, display cetacean (dolphins, whales and porpoises) sounds only as graphs of frequency and amplitude. The CymaScope captures actual sound vibrations imprinted in the dolphin’s natural environment—water, revealing the intricate visual details of dolphin sounds for the first time.
Within the field of cetacean research, theory states that dolphins have evolved the ability to translate dimensional information from their echolocation sonic beam. The CymaScope has the ability to visualize dimensional structure within sound. CymaGlyph patterns may resemble what the creatures perceive from their own returning sound beams and from the sound beams of other dolphins.
Reid said that the technique has similarities to deciphering Egyptian hieroglyphs.
