What is echolocation?
Echolocation is the use of sound waves to find objects and barriers. The sounds are emitted into the air or water, where they are reflected from all objects on their way and returns echoes that reveal the location and size of objects. Some animal species have a sophisticated physiological system that allows them to interpret these echoes with great accuracy. Bats and dolphins are the most famous members of the animal kingdom who use echolocation, but other animals, including humans, are also able to "see" the interpretation of sound waves.
Most bats make high -split sounds and then interpret the returned sound waves or echoes to help them safely navigate in the dark and find their prey. Echolocation also uses dolphins and whales. When one of these animals transmits high -focused sound waves, sound waves are reflected from all objects on the animal's path and are returned to a whale or dolphin. These returned echoes are then converted into a nerve pulsetThe objects of the animal's brain, allow it to avoid obstacles, even in the darkest places and easily find preferred prey. In addition to bats, whales and dolphins, they use echolocation and several birds of a living cave, especially to help them safely navigate in the dark.
people were able to use echolocation in several ways. The US Navy, which uses sound waves for placing underwater objects - especially for placing underwater mines, danger and hostile vessels - has studied marine mammals in an effort to improve their sound navigation and technology (Sonar). In addition, the Marine Mammal Navy program directly used the ability of animal echolocation. The program trained dolphins to serve as a guard and use their echolocation skills to find underwater mines and the designation is for safe removal.
People are capable of echolocation even without the use of technology. People afterThey suffer an acute feeling of hearing and a sophisticated biological echolocation system that has echolocation animals, but some blind people have learned to "see" obstacles and navigate them quite effectively in performing palatal clicks. Carefully listening to returning sound waves allows these people to identify objects that are associated with specific sound wave patterns and determine the exact location of obstacles. Some blind people use echolocation so good that they can safely and confidently ride bikes. Several echolocation educational programs for the blind are already available.
