Tenneco recently acquired the Actran technology in order to predict acoustics & vibro-acoustics. Actran vibro-acoustics provides a rich library of elements, materials, boundary conditions, and solver solutions. The software is used to investigate the effects of design changes at any development stage, and to understand the physics of problems when they occur at the production stage. The Actran computational results are accurate, and have helped Tenneco rely more on simulations than on physical prototypes.

The Actran software helps support our acoustic development programs. Actran helps further improve how we investigate and understand acoustic challenges in order to ensure that we continue to provide leading-edge acoustic solutions for exhaust systems.
