Raja Kumar Can you share the finite element model of the room in an appropriate ASCII format?

René Christensen

Raja Kumar There are only losses if you have applied a lossy medium or impedance on the walls. So check which it is, and then modify accordingly.

Anders Buen

In general the sound absorption in air may either be implemented as a propagation loss, dependant on the distance travelled, or by the mean free pathlength loss dependant on the volume and reverberation time, a statistical oriented measure.
