Very simply, sound is the vibration of any substance. The substance can be air, water, wood, or any other material, and in fact the only place in which sound cannot travel is a vacuum. When these substances vibrate, or rapidly move back and forth, they produce sound. As described in the How We Perceive Sound: The Ear section, our ears gather these vibrations and allow us to interpret them. To be a little more accurate in our definition of sound, however, we must realize that the vibrations that produce sound are not the result of an entire volume moving back and forth at once. If that were the case, the entire atmosphere would need to shift for any sound to be made at all! Instead, the vibrations occur among the individual molecules of the substance, and the vibrations move through the substance in sound waves. As sound waves travel through the material, each molecule hits another and returns to its original position. The result is that regions of the medium become alternately more dense, when they are called condensations, and less dense, when they are called rarefactions.

The Essay on Sound Waves Travel In Different Material
A sound wave is a disturbance. When it travels through air, it bounces the air molecules around and they vibrate. They then hit other molecules and cause a chain reaction. In a different material, such as metal, sound actually travels faster. this is because the molecules are much more tightly packed (water is not dense because the molecules just roll over each other, and air is even less dense, ...
