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.
Acoustic energy is sound energy produced by vibrating objects. The definition of sound says that it is a disturbance of energy that comes through matter as a wave, and that humans perceive sound by the sense of hearing. Sound pressure is the effect and sound power (energy) is the cause. But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms.
