Echolocation is when animals to use reflective sound to figure out the location of an object. Using echolocation, animals are able to navigate through pitch black environments and avoid obstacles. There are many different animals that use echolocation to navigate such as bats, dolphins, and whales. To use this tool animals make a sound. Once they make a sound, they listen for the sound waves that are going to bounce off of their surroundings. The tighter the sound wave, the more information animals are able to pick up on. The tighter sound waves provide a more detailed picture of what is around them, or prey that they are attempting to hunt.
Many people with visual impairment have adapted to the use of echolocation and have developed this tool. Daniel Kish, the blind mountain bike rider uses echolocation to illustrate the world around him. This is useful for people who are unable to see because they can get a better picture of what is happening around them. It is helpful because like Daniel Kish, people can enjoy activities that they may have been told they could never do.
