an explosion is the outward movement of air and hot gasses (roughly in a spherical shape) from the point of detonation. the sound wave is created by the shock wave. at the point of detonation (milliseconds after detonation) there is a vacuum created by the outward shock wave, there will be a slight thunder clap created by the surrounding air rushing in to fill that temporary vacuum.

The relative observability of the light from the explosion, and the sound from the explosion can reach you at different times because the two mediums travel at different speeds.
Light from the explosion travels much faster then the concussion sound waves generated by the explosion. Just light lighting, you'll always see the blast before you hear it, and the time difference is directly proportional to how far away you are.
Here is food for thought... do you first hear or feel the bullet that shot you???

because speed of sound is near about 330 km\h which is very smaller than the velocity of light 300000000 km\h so sound come after explosive is exploded

sound waves are compression waves in air. explosions move a great deal of air, and I guess you can say that they create a great deal of air or gases. the violent motions produced cause waves to propogate in all directions in a wide spectrum of frequencies.

your ears ring because your hearing is damaged, this is called tinnitus.
Because the auditory nerves are damaged temporarily or permanently and they send a continuous message to the brain, experienced as noise or ringing, until the nerves recover or your brain filters the noise out.

speed of light is faster than the speed of sound has to do with physics or something like that sound has more obstacles to deal with

sound travels at 420m per second so it takes some time to reach your ears if you're in some distance

sound is slower then light.
