SEA Coupling Loss Factors
- Using the consistency relationship for coupling between any two subsystems, eta1eta12 = eta2eta21.
- Plate to Room/Cavity
- Room to Plate
- Cavity to Plate
- Room to Room/Cavity (non resonant)
- Cavity to Room
- Plate to Plate (line)
- Structure to Structure (point)
- where
- rho0 = density of air [kgm-3]
- rhos = surface density of a plate [kgm-2]
- m = total subsystem mass [kg]
- c0 = wavespeed in air [ms-1]
- cL = longitudinal wavespeed of a structure [ms-1]
- fc = coincidence frequency of plate [Hz]
- Y = structural mobility
- h = thickness [m]
- S = surface area [m2]
- V = volume [m3]
- sigma = radiation efficiency
- tau = non-resonant room to room transmission coefficient
- gamma = structure transmission coefficient
- rhos = surface density of a plate [kgm-2]
