Computer aided design software now-a days have changed completely the approach to problems of prediction of rooms acoustic measurements . Smart Project engineers use the most recent and accurate software of room modeling to represent complex geometry rooms in 3D. Software used is directly connected to certified and specialized for Acoustic & Sound systems design programs.  Through software like the above engineers can model complicated room acoustic designs in 3D by adding properties of materials to surfaces that consist room construction.  This method is determinant for predicting the acoustic factors like room acoustic behavior parameters.
