Binaural cues are auditory signals that use information from both ears to determine the location of a sound, particularly along the horizontal axis. These cues function by detecting the subtle differences in the vibration patterns that a sound wave creates at each eardrum when a sound originates from an off-center location.

Which of the following best describes the role of binaural cues in sound localization?

There are two types of binaural cues:
1. Interaural Level Difference
2. Interaural Timing Difference 

Types of Binaural Cues

Specific areas within the brain are responsible for monitoring and interpreting interaural level and timing differences. By analyzing these binaural cues, the brain constructs a representation of where a sound originates along the horizontal axis.
