Coarse-grained Langevin-type effective field equations are derived for classical systems of particles. These equations include the effects of thermal fluctuation and dissipation that may arise from coupling to an external bath, as in the Brownian motion of a single particle, or from statistical fluctuations in small parts of an isolated many-particle system, as in sound waves. These equations may provide some guidance for the analysis of mesoscopic or microscopic molecular systems or for systems of hundreds to thousands of subatomic particles produced in high-energy nuclear collisions.
