Take Advantage of NOVA Powerful Acoustic Abilities
Recreate Any Structure
NOVA allows users to faithfully model and analyze the acoustic behavior of any structure, providing a comprehensive tool for accurate evaluation and optimization. Within this framework, two different treatment types address different modeling needs, providing flexibility and accuracy in acoustic performance evaluation.
Users can model a single treatment as a simple series of layers of different materials and types, providing a streamlined approach to understanding the acoustic performance of structural sequences, such as building walls.
Conversely, the software introduces a second type that allows users to create complex parallel combinations that incorporate surface ratios. This advanced feature is tailored for evaluating acoustic performance in complicated scenarios, taking into account imperfections such as uneven distribution of materials or layers within sequences, providing a more realistic representation of acoustic challenges.
Hear the Difference
With the innovative auralization tool, experience the impact of your noise treatment firsthand. While we can’t see sound, our tool lets you listen to the efficiency of your treatment, providing an immersive understanding of the acoustic improvements.
See the Effects of Different Excitations
NOVA empowers you to delve into acoustic performance by offering the capability to apply different excitations like plane wave, diffuse field or turbulent boundary layer allowing for a comprehensive analysis of structures’ response to various real-world acoustic challenges.
In the 2023 NOVA update, we’ve introduced a new excitation method which will allow you to calculate the IIC rating following ASTM E1007 or ASTM E3133.
Designed for NVH Engineers, Acoustic Material Designers and Students
NVH Engineer
Modern vehicles and aircraft frequently incorporate sophisticated vibroacoustic processing systems, implementing a variety of advanced materials such as composites, poroelastic materials, and damping materials. These materials can be arranged in several layers, with the possibility of using different types of multilayers simultaneously. NOVA offers a fast and efficient simulation solution to comprehensively analyze the vibroacoustic properties of these complex treatments.
By identifying the optimal acoustic treatment using NOVA, the engineer can then easily integrate these properties into renowned simulation software such as VA-One, Altran, Sim-Center, Comsol, and others. This seamless integration helps optimize the design process, ensure exceptional acoustic performance and accelerate the development of high-quality products in vehicles and aircraft.
Acoustic Material Designer
NOVA offers an innovative solution to overcome communication barriers between material designers and acousticians, by providing a range of tools to connect the microscopic properties of materials to their acoustic characteristics. For example, thanks to NOVA, it becomes possible to predict the acoustic efficiency of a foam by analyzing parameters such as the size of the cells, their support and the reticulation rate. Similar tools are available for fibrous materials, where fiber thickness, arrangement and density can be used to calculate the overall acoustic parameters of the material.
NOVA also offers the possibility of designing networks of metamaterials and evaluating their absorption or transmission efficiency when integrated into different structures. This integrated approach allows precise design and optimization of the acoustic performance of materials, thus promoting the development of innovative solutions in the field of materials acoustics.
Acoustic Students
NOVA’s fast computing power gives teachers and students the ability to explore in near real time the impact of design parameters on the behavior of structures, whether single or multi-layered. For example, it becomes easy to predict the evolution of the critical frequency of a single wall by sequentially modifying the different design parameters, or to understand how the addition of absorbent materials in a double wall structure influences its transmission level sound (TL).
For researchers, NOVA makes it easy to import their own transfer matrices, whether pressure-velocity type and derived from experiments or generated analytically or numerically. This functionality allows researchers to work with a variety of data, whether from real experiments or simulations, providing essential flexibility for advanced research in structural acoustics.
