DOLPHIN-HUMAN BEINGS COMMUNICATION
WATCH VIDEO. NYT
Denise Herzing, who works with dolphins at The Wild Dolphin Project (Bahamas) and Jupiter (Florida), has spent most of his last 25 years, filming videos of dolphins, looking for food, playing and others, coming to have a growing database that provide a very intimate view on how they teach their children to find food. It is known that dolphins communicate among them using 3 types of sounds: 1) Whistles, to identify each other (like names). 2) Clicks to navigate and find food by echolocation 3) Burst pulses -gross sounds- combination of previous sounds. Researchers believe that there is additional information encoded in these sounds as well as in other ultra-high frequency sounds, inaudible to humans.

Herzing will try the next year to broaden this kind of communication with dolphins testing a 2-way system employing underwater computers that can mimic sounds of dolphins, differentiate and recorded them in real time, as dolphins rarely open their mouths. In the new system 2 human divers placed in front of dolphins, make synthesized whistles, passing then from hand to hand scarves or pieces of seaweeds to establish sound-object associations. Dolphins then imitate the sound asking for certain objects to start a game. Until now man-animal communication is only one way. Herzing, hopes to develop a crude vocabulary for objects and actions with this system.
COMUNICACION ENTRE DELFINES Y HUMANOS
Denise Herzing, que trabaja con delfines en The Wild Dolphin Project (Bahamas) y en Jupiter (Florida), ha pasado la mayor parte de sus últimos 25 años, filmando videos de delfines, buscando comida, realizando cortejos o jugando, llegando a poseer una creciente base de datos que proporcionan vistas muy intimas acerca de como estos enseñan a sus hijos a hallar comida. Se sabe que los delfines se comunican mediante 3 tipos de sonidos : 1) Silbidos, para identificarse entre si (como nombres). 2) Clicks, para navegar y encontrar comida mediante ecolocacion 3) Burst pulses, sonidos groseros mezcla de los anteriores. Los investigadores creen que existe informacion adicional codificada en estos sonidos al igual que en otros de super-elevada frecuencia, inaudible en humanos.
Herzing intentará el próximo año ampliar su base de comunicación con los delfines ensayando un sistema 2 vias con ayuda de computadoras submarinas capaces de imitar sonidos de delfines, diferenciándolos y registrándolos en tiempo real, ya que estos raramente abren sus bocas. En el nuevo sistema 2 buzos humanos colocados frente a los delfines, hacen sonar primero silbidos sintetizados, pasando luego de mano en mano chalinas o segmentos de algas a fin de establecer asociaciones sonido-objeto. Los delfines imitan entonces el sonido para pedir determinados objetos o iniciar algún juego. Hasta hoy las comunicaciones hombre- animal son de una sola via. Herzing, espera desarrollar con este sistema un vocabulario crudo para objetos y acciones.
