Early blindness linked to better pitch discrimination, study finds

• 

  A study found that people with lifelong blindness were better than sighted people at distinguishing pitches.

• 

  Both groups detected tones accurately, but pitch discrimination was better among people who became blind early in life.

• 

  A mathematical model linked the difference to less variability in brain responses to the same pitch, known as internal noise.

• 

  People with more musical experience also showed lower internal noise and better pitch discrimination.

• 

  The findings suggest that enhanced hearing may be specific to tasks involving brain processing rather than a general improvement in hearing.

Who

Researchers led by Woon Ju Park of the Georgia Institute of Technology studied people with and without sight, as well as people with different levels of music training.

What

The study found that people who became blind early in life and people with more musical experience were better at distinguishing pitches.

When

The study was reported on October 12, 2026. The journal article was published online on October 5, 2026.

Where

The research was published in the Journal of Neuroscience.

Why

The researchers linked improved pitch discrimination to lower internal noise in brain responses.
