This complex neurological computation allows humans and animals to navigate space, identify potential threats, and engage in conversation even in noisy settings. The human head acts as a physical barrier, creating a "sound shadow" that causes the sound wave to be slightly quieter in the ear farther from the source.

The Role of the Brain Cortex While the brainstem performs the initial comparison of timing and volume, the superior temporal gyrus—the actual auditory cortex—is where the perception of location solidifies. The Physics of Sound Localization The journey of ear calculation begins long before the signal reaches the brain, rooted firmly in the laws of physics.
This minute discrepancy, often measured in milliseconds and decibels, provides the primary timing and intensity cues that the auditory system uses to triangulate position. These signals are then routed via the auditory nerve to the brainstem, where the initial stages of ear calculation take place before being sent to the auditory cortex for full processing.

By comparing the volume differential between the two ears, the brain can accurately pinpoint vertical location and front-to-back positioning, completing the horizontal plane calculation. For low-frequency sounds, such as a passing truck or a deep drum, the brain detects this delay directly.
