+ - Piezoelectric speaker will let researchers talk with dolphins->

Submitted by

MrSeb writes "A team of Japanese researchers from the Tokyo University of Marine Science and Technology may become the first people to communicate with dolphins using their own language. Dolphins, with many human-like social and sexual traits, are often regarded as one of the most intelligent animals on the planet. The problem is, despite our own vast intelligence, we don’t actually know how intelligent dolphins (or monkeys or pigs or crows) are because we can’t understand their language. Encoded in those whistles, burst-pulse sounds, and clicks, dolphins might regularly discuss calculus and astrophysics — we just don’t know. Now, however, Japanese researchers have developed a “dolphin speaker,” which uses four piezoelectric elements (which apparently have never been used underwater before), and one silver element, to reproduce a dolphin’s ultra-broadband up-to-150KHz “voice” almost perfectly. Next step: Trying it out to see how dolphins react, and then actually working out the dolphin language."
