NOVA

Simulator of Multilayer

Acoustic Materials

Master your Multilayer Materials!

NOVA software allows you to optimize the sound absorption and transmission loss of several material configurations in a very short time due to its user-friendly interface and extremely fast calculation time. No more expensive and time-consuming tests!

​Through the numerical modeling of these materials, different concept proposals can be made with the aim of increasing performance for a given application with respect to cost, weight, efficiency, size as well as other essential criteria.
