Uri is walking home alone on a dark night. He hears a stick breaking and immediately turns to his right to see what made the noise. What cue did Uri most likely use to tell which direction the sound came from?

Question

Quizplus · Accepted Answer

Uri most likely used the slight time difference between when the sound reached each ear, also known as the interaural time difference, to determine the direction from which the sound came from. This is because sound waves will reach the closest ear first, resulting in a time lag between the two ears. The brain then uses this time difference to determine the sound source's location.
