Transmission loss in a cover - Hybrid FE-SEA model

This Hybrid FE-SEA model is representative of an aluminum cover.
The outlet face of the cover is excited by a diffuse acoustic field.
The aim is to compute the transmission loss between the DAF on the outlet face and the semi-infinite fluid (SIF) in the other side.
