Echolocation for the Blind

Guest: Daniel Kish Daniel Kish is blind, but he’s has developed a highly specialized sense of hearing that allows him to echolocate, like a dolphin or a bat –clicking his tongue and using echoes to visualize the world around him. For years Kish has been a popular public speaker, sharing his gift with the world and encouraging others. Since we last spoke with him three years, Kish participated in a study at Durham University in England that seems to validate his technique. So we figured it was time for an update.
