Final answer:
Echolocation benefits humans by aiding in navigation and obstacle detection.
Step-by-step explanation:
Echolocation, the use of reflected sound waves to locate and identify objects, is used by animals such as bats, dolphins, and whales. It is also imitated by humans in technologies like SONAR and radar. For example, SONAR is used by submarines to detect objects underwater, while radar is used in weather forecasting and air traffic control.
Furthermore, echolocation technologies are being developed to help visually impaired people navigate their environment. By emitting a sound and sensing the reflected sound waves, individuals can gain a sense of their surroundings and locate obstacles.
