It’s porentially even harder than this. Not only do we have two ears, our ears are shaped to help determine where sounds are coming from, and we make constant movements to further help process audio. I remember years ago I played an FPS capture the flag type game with headphones, and, not everyone knows this, but the math works out that the same sound could come from in front or behind, so I developed a strong tendency to make small mouse movements rotating left and right to help me identify where footsteps were coming from. I didn’t even know I was doing it until I talked to an audio engineer who mentioned this problem, and next time I played, I realized how much I relied on it to avoid getting blindsided.
