Sound wave propagation is a wave process. The acoustic signals requires a mechanical elastic medium for propagation and cannot travel through a vacuum unlike, electromagnetic light waves. Sounds travels more quickly in solids, followed by liquid than through gases. The velocity of sound, in a wave form is 331.29 {ms}^-1 through dry air at {0}^oC Sound wave concept When vibration disturbs particle in a medium, then the particle displaces other surrounding particles in that medium. A wave pattern is then formed, when the particle moves in the outward direction continuously. The wave carries the sound energy through the medium from the source and become less intense. The sound energy solely depends on the volume of the volume of the sound; the higher the sound energy the louder the volume. There are three concept of sound wave that causes a sound to be produced. They include: frequency (f), wavelength  \lambda and amplitude (A). The sound wave vibrates at different frequenc...
