The article provides a comprehensive review of auditory localization, a fundamental ability that allows humans to perceive the spatial location of sound sources in their environment. It covers the mechanisms and acoustic cues used by the human perceptual system to achieve accurate auditory localization. The review discusses monaural and binaural perceptual mechanisms, including Interaural Time Difference (ITD), Interaural Level Difference (ILD), and Head-Related Transfer Function (HRTF). It also examines secondary elements such as reverberation and motion, and their impact on localization. The article presents the perceptual limits of localization abilities and describes reference systems and pointing methods used in experimental research. Additionally, it explores cases of misperception and auditory illusions. The review aims to provide practical information for experiments and work in the auditory field, emphasizing the importance of these mechanisms in both theoretical research and practical applications, such as immersive technologies and sensory augmentation devices.The article provides a comprehensive review of auditory localization, a fundamental ability that allows humans to perceive the spatial location of sound sources in their environment.
