The Soundex is a coded surname index (using the first letter of the last name and three digits) based on the way a name sounds rather than the way it's spelled. Surnames that sound the same but are spelled differently - such as Smith and Smyth - have the same code and are filed together.
What Is Sound? Sound is a pressure wave which is created by a vibrating object. This vibrations set particles in the sur-rounding medium (typical air) in vibrational motion, thus transporting energy through the medium. Since the particles are moving in parallel direction to the wave movement, the sound wave is referred to as a longitudinal wave. The result of longitudinal waves is the creation of compressions and rarefactions within the air. The alternating configuration of C and R of particles is described by the graph of a sine wave (C~crests, R~troughs) The speed of a sound pressure wave in air is 331.5+0.6T c m/s , T c temperature in Celsius The particles do not move down the way with the wave but osciallate back and forth about their individual equilibrium position.
