Abstract [en]

A new Statistical Energy Analysis (SEA) formulation for double walls isderived. The new formulation uses three elements to describe the double wall,one for each plate and the third for the cavity including the mass-controlledmodes of the plates. This means that the influence of the double wall resonance(mass-air-mass resonance) can be predicted by SEA. Calculations aremade and compared to measurements, showing fair agreement.
