The difference in the speed of sound and the speed of light. Light travels much faster than sound, so you will see it, and then hear it. The further away, the greater the time difference.
An observer sees an explosion before hearing it because light travels much faster than sound. Light travels at approximately 299,792 kilometers per second (about 186,282 miles per second), while sound travels at about 343 meters per second (around 1,125 feet per second) in air. This significant difference in speeds means that the light from the explosion reaches the observer almost instantly, while the sound takes longer to arrive. As a result, there's a noticeable delay between seeing the explosion and hearing it.
The time difference is due to the differences in the speed of light and sound. Light travels near 300,000,000 meters/second where sound travels 343 meters/second. Light travels almost one million times faster than sound therefore it reaches you first.
Seeing and hearing are important but not necessary to live a full life. Seeing and hearing gives you the ability to drive a car, ride a bike, work a job, and watch your kids grow up.

The word "perception" involves both hearing and seeing, as it refers to the way we interpret and understand sensory information received through our various senses, including both vision and hearing.
The occipital lobe is important for seeing, as it processes visual information from the eyes. The temporal lobe is important for hearing, as it processes auditory information from the ears.
it would be weird if you been seeing or hearing things. But put yourself in Helen Keller shoes and see how it feels for the rest of your life
Judaism emphasizes both; but hearing is paramount for Torah-learning.
