PAFEC VibroAcoustics - Architectural - Analysis of a small room

The figure shows a model of a small room, with the ceiling removed. It is based on a 6m x 4m x 2.5m cuboid, with the extra features of a rounded corner, a cupboard, a fireplace and a window.

The boundaries are assumed to be rigid, apart from the window made of glass and the floor which has been analysed with two admittance values, representing two types of flooring.

The air is modelled with an acoustic boundary element mesh, composed of quadratic patches.

The window was modelled with structural shell elements which are analysed as fully coupled to the fluid (air) elements.

The frequency range analysed was from 10Hz. to 150Hz in 0.5Hz steps.
