Can we see with our ears?
Although the ears are doing all the work in detecting signals from the outside world, it is the brain's visual centres that light up when viewed using functional MRI (fMRI) scanning – a technology that shows which brain areas are most active while performing a specific task.
How do blind people use hearing?
Blind people use auditory information to locate sound sources and sound-reflecting objects (echolocation). Sound source localization benefits from the hearing system's ability to suppress distracting sound reflections, whereas echolocation would benefit from “unsuppressing” these reflections.
What uses their ears to see?
Bats use their ears to "see" in the dark. ... They use their ears for something called echolocation. Notice the two smaller words that make up this bigger word—echo and location. Bats listen for an echo, or reflected sound, to find where an object is.
