	Some prerequisities need to be in place before you can assign an Acoustic Excitation.
- Create a Harmonic Acoustics analysis
 - Add Air to Engineering Data and make sure it has Speed of Sound and Density physical properties
 - Assign Air to the Solid Body representing the room
 - Assign an Acoustic Region to All Bodies
 - Mesh the Solid Body
 
Now you should be able to assign a Mass Source.
Some of that is automated if you use Ansys 2023 instead of 19.2 with the ACT.
