Sound attenuation, as defined by Stoke's Law, is the loss of intensity -- or attenuation -- of a sound wave travelling through a Newtonian fluid, most commonly air. The described theory of sound attenuation was first derived by Sir George Stokes, while studying the dynamics of Newtonian fluids. These equations were first noted in joint papers that Stokes published with Claude-Louis Navier. Practical applications of sound attenuation calculations include the configuration of speakers in a home theatre system.
