Actually, sound does not travel faster than light. The speed of sound in air is approximately 343 meters per second (at room temperature), whereas the speed of light in a vacuum is about 299,792,458 meters per second. Light travels much faster than sound.
The reason we often see things before hearing them is because light travels significantly faster than sound, and our visual system processes information more quickly than our auditory system. When an event occurs, such as a distant object falling, the light reflecting off the object reaches our eyes almost instantaneously, allowing us to see the event immediately. However, sound waves generated by the falling object take some time to travel to our ears, especially if the object is far away. The speed of sound is considerably slower than the speed of light, so the sound waves take longer to reach us.
This time difference between the arrival of light and sound is what causes us to perceive visual events before auditory events. Our brain processes visual information more rapidly, allowing us to see things before we hear them. It's important to note that the exact time difference between visual and auditory perception depends on various factors, such as the distance between the event and the observer, as well as the speed of sound in the medium through which it travels (e.g., air, water).
In summary, although sound waves and light waves travel at different speeds, it's the relative processing speed of our visual and auditory systems that leads to the perception of seeing things before hearing them.
