Binaural cues are auditory signals that help us locate the direction and distance of sounds. They rely on the differences in the sound reaching each ear, such as the time it takes for a sound to arrive and the intensity of the sound at each ear. These differences allow our brain to interpret where a sound is coming from in three-dimensional space. The two main types of binaural cues are interaural time difference (ITD) and interaural level difference (ILD). ITD refers to the slight delay in sound reaching one ear compared to the other, while ILD involves the difference in loudness between the ears. Together, these cues enhance our ability to perceive our environment.
