Although we know the physics inside a media where the sound waves propagate, determination of material\'s or structure\'s sound reduction index is not an easy task. The lack of good engineering solutions proves the point.

The only reliable way to calculate the sound reduction index is to carry out an experiment.Therefore, the aim of this study is to develop a mathematical model that can measure sound reduction index and improve building element sound reduction index.
