The research field of Numerical Acoustics deals with the development, improvement and optimization of numerical simulation tools for acoustical problems.

Modern numerical methods, like the Finite Element (FEM) or Boundary Element (BEM) method, enable the accurate and physically well-founded simulation of acoustical wave propagation in air, fluids and solids.

The accurate modeling of boundary conditions, of the coupling between models for fluid and structure-borne sound and of damping mechanisms is subject to current research as well as the investigation and implementation of efficient numerical methods for the solution of the corresponding systems of equations.

The previous figure shows a simulation example in a small recording studio. The couloured zones visualize the sound pressure distribution in the room at a frequency of 139 Hz.

The second figure shows the simulation of the vibration behaviour of an elastical dividing wall separating two small cuboid rooms.

The simulation software SoundSolve used for both examples is developed and maintained here.
