All of the choices contribute to our ability to localize sound. Our ears on each side of our head allow us to receive sound from different angles, while comparing the signal received by the left and right ears helps us determine which direction the sound is coming from. Turning our head also helps us determine the direction of the sound by detecting how the arrival of the sound at the two ears changes.
