Many frequently ask about dolphins and dolphin sounds. Dolphins have the ability to send and receive sonic frequencies of 180,00 cycles per second. That is 10 times faster than humans can perceive–human hearing ends at about 16,000 cycles per second. Dolphins have the ability to project multi-dimensional holographic images on their sounds. In a series of clicks, a dolphin can encode encyclopedic information upon sound. And another dolphin can receive and understand this information.
