It is long known stories from blind peoples all over the world that all blind people hear better than normal sighted people.

Neuroscientist found evidence that the portion of brain Visual Cortex which responsible for vewing is also doing auditory tasks like Echolocation that is detecting motion by reflecting sound wave and serve to find out the direction of sound wave for those who were blind or visially impared peoples.

Visual Cortex of the brain of those blind peoples either blind from birth or visually impared by accident automatically developed to synchronize with sound wave.

Reseracheres scanning with poerful MRI techniques for some blind people's brain during testing and find evidence that not only visual cortex synchronizing with auditory cortex of those blind people to detect sound wave better than normal sighted people.

Reserachers also watched that auditory cortex of blind prople is more efficient than normal sighted people.
