This finite element based program allows for the analysis of sound traveling through various media including fluids, solids and foam-like substances, for an overall approach to sound management. Comet SAFE® allows users to design optimal noise control treatments with such elastic porous materials as glass fiber, mineral wool, and a variety of cell foams. The development of SAFE was partially funded by National Aeronautics & Space Administration (NASA).
