Are blind individuals hearing better?
The feeling of sound happens as the sound vibrations enter our ear and cause small hair-like structures–called hair cells–to move back and forth within our inner ears. This movement is turned by hair cells into an electrical signal the brain can use. How well a individual can hear relies mainly on the intactness of these hair cells. They don’t get lost once–and for blind people this isn’t anything else. Blind individuals can’t hear better physically than other people.
But, in listening duties such as locating the sound source, blind individuals often outperform visionary individuals. The reason for this arises when we see what is taking place with the brain over and beyond sensory organs and how it processes sensory data. Perception happens when the brain interprets signals from our bodily bodies and distinct sections of the brain react to the data from various human bodies. There are regions where visual data (vision cortex) is processed and regions where noise data (auditory cortex) is processed. However, the brain reorganizes the tasks of these brain fields once a feeling of sight goes missing.
