lauwa006: February 2012 Archives

Many of us go through life taking sight and vision for granted. But what about those people that do not have eyes with which they can see? Perhaps there is another way in which these people can "see" the world around them. This is the case for a boy named Ben Underwood. ben underwood.jpgDue to cancer, Ben lost both of his eyes at the age of two. By the age of six, Ben started using "clicks" that he would produce with his mouth in order to "see" objects around him. Ben uses these clicks to bounce off of objects and then listen for the returning sound waves. By doing this, Ben is able to produce a mental picture in his head of the relative sizes, shapes, and locations of what is around him. Echolocation, as this phenomenon is called, is also used by animals such as bats and dolphins.

Ben's ability to use echolocation is just one of the many examples of how humans are able to concentrate more on one sense to compensate for the loss of another. I do not want to give the false impression that Ben has a superhuman sense of hearing. In fact, Ben's hearing is very similar to the range of an average human's. Rather, Ben has been able to concentrate more attention to his hearing capabilities to compensate for his loss of vision. This phenomenal ability allows Ben to participate in many activities he might otherwise not be able to enjoy such as karate and rollerblading.
