How do I determine transmission loss on the full frequency range

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... read more

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

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... read more

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

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... read more

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

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... read more

How do I choose the BEM solver for my application and how can I parallelize my BEM solve

How do I choose the BEM solver for my application and how can I parallelize my BEM solve
Boundary Element Analysis (BEM) is considered the industry standard for low frequency acoustic radiation however, the effectiveness of BEM is often constrained by the availability of computational resources capable of processing increasingly large models.... read more

How do I recover stress responses formed by sensitive space structures

How do I recover stress responses formed by sensitive space structures
A high intensity diffuse acoustic field surrounds a rocket during the initial launch stage. The intensity of this field is capable of compromising the integrity of composite fairings used to protect the payload and can also cause failure of composite... read more

How can I predict flow induced noise in aircraft interiors

How can I predict flow induced noise in aircraft interiors
Flow induced noise is a major contributor to interior noise in aircrafts. This webinar will demonstrate how VA One can be used to model the effect of noise arising from interaction, from a surrounding during flight conditions using source models of... read more
