Human auditory localization is the ability to determine the origin of a sound in the environment. This process relies on several cues, including the differences in the time it takes for sound to reach each ear, known as interaural time differences, and the differences in sound intensity between the ears, called interaural level differences. Additionally, the shape of the outer ear, or pinna, helps to filter sounds, providing further information about their direction. The brain processes these cues to create a three-dimensional perception of sound, allowing individuals to identify where a sound is coming from in their surroundings.
