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.
Main Advantages of NOVA
Exploit All NOVA Possibilities!
Allows unlimited combinations of different layers of materials
Allows unlimited combinations of different layers of materials such as elastic materials, visco-elastic foams, fibrous, felts, screens, septum, solids, perforated panels and fluids to simulate acoustic problems of the daily life.
Takes into account orthotropic, sandwich and composite panels.
Works with frequency dependent properties.
Includes automatic detection and joining of different domains (elastic and fluid).
Investigate the effects of different boundary conditions and multiple types of excitation (plane waves, diffuse acoustic field, mechanics, pistons, point source, turbulent boundary layer, etc.).
Offers a wide selection of excitations.
Includes an extensive material database.
Includes scripts to calculate SEA input parameters: modal density, loss factor, radiation efficiency, wave number.
Includes a script that allows the study of heterogeneous materials by the parallel transfer matrix method (PTMM).
Includes micro-macro (bottom-up) scripts for foams and fibers.
Accounts for the effects of panels with finite side dimensions in the high frequency module.
Allows the simulation of impedance and bazooka tests, attenuation index and absorption under any incidence.
Analysis in thin bands and in 1/3 octave.
Calculates a large number of parameters: absorption and reflection coefficient, surface impedance, attenuation index, dissipated powers, equivalent damping factor, space velocity and pressure response, insertion loss, radiation efficiency, etc.
