Beakus provides an efficient and easy-to-use computer based tool for solution to exterior acoustic problems. Beakus includes the direct boundary element and finite element methods. It is able to predict sound pressure radiated from a vibrating structure. The advanced yet user-friendly interface and many tools enable very fast numerical computation for accurate noise prediction. Typical applications include computing sound levels in the passenger compartments of automobiles and aircraft, eigenvalue problems and radiation problems. The effect of sound absorbing surfaces, open windows, partial enclosures and other bodies can be included in the simulation.
