Interaural Time Difference

Interaural Time Difference (ITD) refers to the slight difference in time it takes for a sound to reach each ear. When a sound comes from one side, it reaches the closer ear slightly sooner than the farther ear. Our brain detects this timing difference, allowing us to pinpoint the direction of the sound. ITD is particularly effective for low-frequency sounds, helping us locate where a sound is coming from in our environment, which is crucial for understanding speech, detecting potential dangers, and navigating our surroundings.
