Humans Can Learn to 'Echolocate' in Just 10 Weeks, Experiment Shows
With enough training, most humans can learn how to echolocate, using their tongue to make clicking sounds and interpreting the echoes that come back, reflected from the surrounding environment. In as few as 10 weeks, researchers have been able to teach participants how to navigate obstacles and recognize the size and orientation of objects using the rebounding calls of their clicks.
Restoring Hearing With Beams of Light
There's a popular misconception that cochlear implants restore natural hearing. In fact, these marvels of engineering give people a new kind of "electric hearing" that they must learn how to use. Natural hearing results from vibrations hitting tiny structures called hair cells within the cochlea in the inner ear.
