When I first picked up this book and began reading, echolocation really caught my attention. I was a little confused about it at first but then I read about the study done in the laboratory of Karl Dallenbach at Cornell University. Since the participants, at first, believed that it was the facial vision that was preventing them from making contact, I believed that as well. It seemed very legitimate and possible. When I read that the participants collided with the wall every time after they took off their shoes and put headphones on so they couldn't hear, I was very shocked. I can definitely understand that hearing would help a person figure out their surroundings, but I did not think it would be one of the only senses. I never realized how important sense of sound really is. I know it is necessary for survival, but reading about this study made me realize how important it is for other things as well.
