Two cavity systems connected via a plate system and transfer paths of SEA coupling

SEA Area Junctions

Introduction Area Junctions are special in SEA theory. For cavity-plate-cavity connections there are not only direct paths. This violates the principle SEA assumption that only connected subsystems can exchange energy An intrusive way to understand the different paths is the transmission formula from Cremer. and are mass per area, fluid density and speed of sound,

New release: pyva 1.2.2 can now handle plate perforation

In many applications plates or impervious screen layers are perforated. That means there is a fraction of motion given by the flow through theperforation of the plate. This is done by using the perforation keyword in the definition of the related infiniteLayers class. Usually, a plate or mass layer is described by a transfer impedance
