Sound radiation from ribbed plates to flat plates.

One would expect a ribbed plate to radiate less noise as compared to a normal plate with no ribs. But when I analyse a box with ribbed plates, it radiates more sound as compared to a box with normal plates. Why?

How does VA One calculate hybrid TL for a DAF loaded FE panel connected to two SIFs?

Hybrid transmission loss provides an efficient way of predicting the transmission loss of a complex panel modeled in FE Structure. The main advantage is provided by the SIF and its capability to connect with FE subsystems (i.e. no modeling of the acoustic field with FE acoustics is required). How is this calculated?

How do I run the RAYON solver in Linux?

RAYON is the BEM solver inside VA One, the BEM intermediate solution can be solved in Linux using RAYON.
