Sound localization is the ability to identify the origin of a sound in the environment. This process relies on the brain interpreting differences in the time and intensity of sound waves reaching each ear. For example, if a sound comes from the right, it will reach the right ear slightly sooner and louder than the left ear, helping the brain pinpoint its location. Several factors influence sound localization, including the shape of the outer ear, which helps filter sounds, and the head's position, which can create sound shadows. This ability is crucial for various activities, such as communication, navigation, and survival in both humans and animals.
