Why do blind people usually have good hearing?

Sometimes we have to be amazed at how many blind people have great sound recognition abilities.

Recent research by Alexander Stevens, an expert at Oregon Health and Science University, explains the reason for early blindness that hearing develops more than other normal people.

The cause lies in the occipital part . Normally, cerebral palsy has a very important function of warning every time a person is affected by a certain image signal. Thanks to this warning, people will be more sensitive and proactive in their ability to receive and process images.

However, for people who are blind or blind from an early age, due to the loss of early vision, this part has been used for other purposes, becoming an " alarm bell " for audio signal.

In his research, Stevens applied brain scans of blind people every time there was an impact sound, the results from scanners showed that their occipital part was very active for the blind. superior listening ability.
