PAFEC VibroAcoustics - Architectural - Analysis of a small room

A small recording studio, shown below, has been analysed over the frequency range of 3Hz to 200Hz. The back wall of the studio is lined with absorbent material (rockwool). Other surfaces were assumed to be hard and reflective.

The air and rockwool are modelled with an acoustic finite element mesh.
