Sound!!!!

Sound, sound starts with a vibration that later on ends up with a human being hearing. The way the sound goes through our ear is that. First the sound goes into the ear canal, then into the eardrum so that you get the frequency, then it goes through the stirrup and then into the anvil and in the anvil there are tiny hairs that sway when sound comes in and then the hairs send the sound to the brain.
The speed of sound depends on the Elasticity, if you dont know what Elasticity is, then i will tell you, Elasticity is the ability of a material to bounce back after being disturbed. Also in the speed there is density and temperature.
Density in a medium is how much matter, or mass there s in any amount of space or volume.
