Hearing is the fastest human sense. A person can recognize a sound in as little as 0.05 seconds. Compare this to the other senses. It takes about 0.2 seconds for your brain to understand the light that reaches your eye. It also takes about 0.2 seconds for your brain to recognize something touching your hand or foot.
It’s because hearing or seeing only starts when a sound or light reaches your ear or eye. It doesn’t matter how fast the light gets to your eye. The only thing that matters is how long it takes to get from your eye to your brain. It’s the same with hearing. It doesn’t matter that sound moves slower than light. The only thing that matters is how long it takes the information to get from your ear to your brain.
