Dolphin echo location Seeing without eyes? Regardless of what type of sound a dolphin makes in its diverse vocal repertoire, sounds are generated in an anatomically unique way compared to other mammals. Dolphin sounds and hearing, also known as SONAR and echolocation, provide dolphins with sophisticated communication techniques that are similar to how people communicate with each other. demonstrated echolocation in dolphins by covering a dol-phin’s eyes with rubber suction cups and observing that the animal could avoid obstacles in a maze—all the while emit-ting ultrasonic sounds. The dolphin hearing range is also broader than that of many species, which allows them to hear specific sound sand frequencies that humans cannot. If you were a dolphin, and you lived in the murky waters of river deltas, or the blackness of the deep ocean, your eyes would be useless.You wouldn't find food, you wouldn't even find your fellow dolphins.

Those early beginnings of dolphin echolocation research are … Marine mammals, such as whales, dolphins, and porpoises, are much more dependent on sound for communication and sensation than are land mammals, because other senses are of limited effectiveness in water. Auditory evoked potential (AEP) responses were recorded during echolocation in an Atlantic bottlenose dolphin ( Tursiops truncatus ) trained to accept suction-cup EEG electrodes and detect targets by echolocation. Whale sounds are used by whales for different kinds of communication..

2) When the sound hits an object in the water, it bounces back to the dolphin as an echo.

AEP recording was triggered by the echolocation clicks of the animal.

dolphin echolocation data card . in length. dolphin echo location. Dolphins use sound to detect the size, shape, and speed of objects hundreds of yards away. In dolphins, Echolocation is most effective at close to intermediate range, about 5 to 200 m (16–656 ft.) for targets 5 to 15 cm (2–6 in.) The distance that sound travels in the ocean also depends on the water temperature and pressure. The dolphin's natural sonar, called echolocation, is incredibly precise The dolphin's echolocation process goes like this: 1) The dolphin uses nasal passages to make a click and sends it through its forehead, which focuses the sounds together into a beam before sending it into the water. The mechanisms used to produce sound vary from one family of cetaceans to another. Other sounds, such as clicks and buzzes, are used for echolocation, a form of active biosonar that is important for hunting fish [1].
