The sound wave behavior at low frequencies in small sound recording, control, and reproduction rooms, results in resonant sound fields observed in both frequency and spatial domains. Finite Element Method (FEM) software applications provide potential analysis procedures for acoustics problems but there is a lack of tools focusing on room acoustics investigation. The present work is the result of an attempt to develop a room acoustics modeling tool integrated with a FEM. Simple room construction, common acoustical treatments, and multiple source excitations are involved in modal and steady state analysis procedures in order to simplify the solution of problematic sound fields. The key parameters and features, as long as validation experimental results are presented.
