Sound is simply a physical disturbance in a medium (e.g. air, water) that is capable of being detected by the human ear. Air can carry these vibrations simultaneously. Every vibration that follows causes the air surrounding it to compress and expand. These compressions and expansions located near the source of the sound continue to compress and expand the air farther away so the vibrations travel through the air as sound waves. These waves travel along ...
