If you were to travel at the speed of sound, you would not experience everything around you appearing to happen slowly. Instead, you would experience a different phenomenon known as time dilation, which is a consequence of special relativity.
According to the theory of special relativity, as an object approaches the speed of light, time appears to slow down relative to an observer who is at rest. However, this effect becomes significant as the object approaches the speed of light, not the speed of sound.
The speed of sound is relatively slow compared to the speed of light. In fact, the speed of sound in air is approximately 343 meters per second, while the speed of light is about 299,792,458 meters per second. So, traveling at the speed of sound would not cause a noticeable time dilation effect.
It's important to note that time dilation effects become more significant as an object approaches speeds closer to the speed of light. For example, astronauts traveling at very high speeds relative to Earth's surface or in space can experience measurable time dilation effects, but those speeds are far greater than the speed of sound.
