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.

Escavator CAB - SEA model

This SEA model is representative of an excavator cab.
The aim of this model is to predict energy flow and sound pressure in the cabin interior due to structure-borne noise.

Vibro-Acoustics

Elevator Cabin - Hybrid FE-SEA Model

This Hybrid FE-SEA model is representative of an elevator.
The aim of this model is to predict structural velocity response of the frame holding the cabin (FE structural modes contribution) and sound pressure in the cabin interior space (Hybrid FE-SEA ) due to structural mount excitation....
