Echolocation is a process used by bats and many other animals to locate and identify an object. An animal would send out a high-pitched sound known as ultrasound which bounces off a thing and the animal would receive an echo. This incredible ability not only allows animals like bats and dolphins to “see” in complete darkness but also to communicate with each other. Echolocation is especially important to bats because it helps them hunt tiny insects in dark caves. Other than bats, there are many more animals who use echolocation to track down objects including whales, narwhals, shrews, porpoises, and swiftlets. Echolocation is an amazing ability a group of animals use to detect items without using their eyes. Although echolocation has many advantages, I would still rather have vision if I could choose between them. There are three reasons why I would say that.
First of all, I would not be able to see things that ultrasound waves couldn’t detect such as colors, written text, pictures, and patterns. I couldn’t see a beautiful piece of artwork or enjoy any spectacular and breath-taking scenes of nature by echoes. Echolocation can’t detect these things because the ultrasound waves can’t bounce back from those things and analyze the information. Also, echolocation could not keep track of subtle and micro things and smooth, vertical surfaces. In my opinion, vision is better than echolocation because it is more direct and convenient.
With echolocation, I am not able to recognize people’s emotions and see animal’s cute looks. This is also a downside of echolocation. Appearances are things that ultrasound waves couldn’t detect. I would miss enjoying animals’ cute looks. Also, you can’t distinguish people’s appearances and “see” a specific look of them while using echolocation. You could only identify people’s facial expressions by using vision. What’s more, you could only feel a person’s emotions with eyes. You could read the different feelings through the expression on someone’s face. This is very important to humans when they are connecting with each other. This is another reason why I would rather have my eyes instead of echolocation.
Another reason why I wouldn’t want to choose echolocation is it could cause information leakage. Information leakage often happens when there is a group of ultrasound speakers. It refers to when an echo goes to a different receiver instead of the speaker and the wrong echo goes back to the speaker. Therefore, the receiver would get the incorrect data which would cause a lot of confusion and probably make the receiver run into an obstacle. This shows that echolocation is not as accurate as vision. With eyes, it is more certain and precise when there is a group of animals or people. You wouldn’t see anybody else’s view while using your own eyes. Using vision to detect things is easier and less confusing than echolocation.
Echolocation is an amazing ability that allows some animals to “see” and detect objects in complete darkness. Although echolocation is helpful in some ways, I would rather have my eyes and use vision. Using echoes couldn’t detect things that are on a flat surface like words, pictures, and colors. Echolocation couldn’t detect anything’s appearance or what it looks like. Using vision is more accurate than echolocation. There won’t be any information leakage while using vision. In my opinion, vision is better than echolocation. But on the other hand, it would also be cool if I could use vision and echolocation together. I could both detect things in the dark and see beautiful scenes and pictures. Echolocation and vision would work very well if used together.
