Which brain region contains the primary auditory cortex for processing sound?

The temporal lobe contains the primary auditory cortex for processing sound.

The primary auditory cortex lies on the superior surface of the temporal lobe, within the transverse temporal gyri, also called Heschl’s gyri. Signals relayed from the ears reach this region through the auditory pathways, where basic features such as frequency and intensity begin to be represented.

The temporal lobe does much more than process hearing. It also contributes to language comprehension, visual recognition, memory, and emotional processing. The auditory cortex is bilateral, so both temporal lobes participate in hearing, although the two sides can have different specializations.

A common mix-up is placing all sensory processing in the parietal lobe. The parietal lobe is strongly associated with touch and spatial processing, while the occipital lobe is primarily visual. Sound interpretation begins in the temporal lobes and is then integrated with language and other cognitive systems.
