How do I model complex floating floor configurations

Designers in both the aerospace and rail industries use complex honeycomb or extruded panels for floating configurations. Due to the complexity of these designs, obtaining accurate vibro acoustic performance models can be challenging. See how the periodic module in VA One can be used to provide a de...

How do I determine transmission loss on the full frequency range

Research has shown that the low frequency performance of noise control treatments is an important consideration above certain frequency thresholds. Adding non-structural mass for cavity absorption and damping ratios for the trim effect on structures does not represent the physics accurately. See ESI...

How do I determine a structureborne response of a fully trimmed vehicle

The use of low frequency models to predict structure born performance of trimmed structures is often ignored due to the complexity of deploying deterministic models of structure, multilayer noise control treatment and interior civility that are harmonised to provide overall vibro acoustic performanc...

How do I create a vibro-acoustic model of a loudspeaker

In many applications, public address systems need to be audible at each passenger location. Test based qualification can be expensive if the response needs to be measured at many different locations across several different product configurations.  See how VA One can be used to create effective mode...

How do I define the damping model in my vibro-acoustic analysis

The definition of damping in a vibro-acoustic model is crucial for predicting accurate results in simulations. However, getting information about the real damping of a structure is often a bottleneck, thus inducing high importance of having the right tools to define the damping in a model. This W...
