Here’s what you’ll learn when you read this story:It’s possible for humans to develop echolocation as a type of sixth sense. It took a bit of creativity to transform the soundwaves back into something the human participants could recognize. For comparison, bat echolocation signals in the wild range from 9 kHz all the way to 200 kHz—well outside our range of hearing of 20 Hz to 20 kHz. The next step for this research is to give participants freedom to move around when they’re interpreting these echolocation signals, Sumiya says. That will more closely mimic the action bats might take when using echolocation “because echolocation is ‘active’ sensing.”How Visually Impaired People Develop a New SenseLosing one sense can heighten others.
