Simulator of Multilayer Acoustic Materials

NOVA-MainWindow-1

NOVA software allows you to optimize the sound absorption and transmission loss of several material configurations in a very short time, thanks to 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.

2023: New Interface

NOVA Software is designed to solve various types of acoustic problems following a simple workflow indicated by the left menu bar.

An innovative drag & drop system has been developed to create and edit noise control treatments with an intuitive visual representation. User can create or modify a noise control treatment by dragging material from the database to create layers, or by dragging existing layers.
