Traveling to the brain

Electrical impulses travel along the auditory nerve and pass through many brain centers that process information. Signals from the right ear travel to the auditory cortex. The auditory cortex is in the temporal lobe on the brain's left side. Signals from the left ear travel to the right auditory cortex.

The auditory cortices sort, interpret and file information about the sound. This process lets you detect certain sounds. It also lets you block other sounds as background noise.
