Unscramble the Blue Letters


A sound from directly in front of you will reach both your ears at the same time. You’ll also hear it at the same intensity in each ear. However, a low-frequency sonud coming from one side will rceah the near ear monercdscios before the far one. And high-frequency sdouns will sound more intense to the near ear because they’re blocked from the far ear by your head.

These strands of information reach scipael parts of the brtineasm that analyze time and intensity differences between your ears. They send the results of their analysis up to the auditory cortex. Now, the brain has all the information it needs: the ptraetns of activity that tell us what the sound is, and information about where it is in space.

Original Text


A sound from directly in front of you will reach both your ears at the same time. You’ll also hear it at the same intensity in each ear. However, a low-frequency sound coming from one side will reach the near ear microseconds before the far one. And high-frequency sounds will sound more intense to the near ear because they’re blocked from the far ear by your head.

These strands of information reach special parts of the brainstem that analyze time and intensity differences between your ears. They send the results of their analysis up to the auditory cortex. Now, the brain has all the information it needs: the patterns of activity that tell us what the sound is, and information about where it is in space.
