Service portfolio: Acoustics

We analyze, optimize, and document the acoustic properties of your products, rooms, or systems – using state-of-the-art simulation technology and precise measurement technology for airborne and structure-borne sound, room and building acoustics, and electroacoustic systems.


Learn how we can support you with virtual acoustics using a concrete room acoustics use case.

Simulation mit COMSOL Multiphysics®

Whether reverberation, sound radiation, or structure-borne sound – acoustic behavior can be simulated, understood, and specifically improved. Using physically sound acoustic models in COMSOL Multiphysics®, we calculate sound propagation in air, solids, and coupled media. This creates clarity – even in the planning or development phase.
We offer practical, simulation-based support for the optimization of rooms, products, machines and systems – including visualization, frequency analysis and optional coupling with mechanical and thermal effects.
