• The uses of the architectural layout and the interior components were the tools to apply a good acoustical environment, using the science, within the historical periods.

• Interior acoustic design needs a clear classification of functional necessities to

• The coefficient of absorption (alpha ᾱ) factor permits to apportion the material scheme within the interior. Alpha differs upon the level frequencies. When overall alpha magnitude reaches the round of "1," it means the material is absorber, and when reaching the round of "zero," it means the material is reflector.
