Acoustic theoryAcoustic theory is a mathematical field that relates to the description of sound waves. It derives from fluid dynamics. See acoustics for the engineering approach. Propagation of sound waves in a fluid (such as water) can be modeled by an equation of continuity (conservation of mass) and an equation of motion (conservation of momentum) . With some simplifications, in particular constant density, they can be given as follows: |
