Expert Answer:

Sound wave is defined as a vibration that propagates as an audiable wave of pressure,
through a medium such as a gas, liquid or solid.
 
When we speak, our vocal chord is vibrating and pressure wave is created in air as audiable sound wave.
 
when wires under tension are made to vibrate, we hear sound waves from string instruments.
 
Air vibrations in pipes create sound waves in piped instruments.
 
Sound waves are longitudinal waves .
 
In logitudinal waves,  direction of pressure vibration is same as the direction of propagation.
