Large and small room acoustics

The final degree project is consisted on studying the acoustics of class rooms of differnet dimensions. Study has been carried out on how to improve these class rooms acoustics by using absorbent material such as resonators and porous abosorbents. Reverberation is one of the most important phenomenon occurring in rooms that is important to correct. In this regard, one possibility could be the absorption of acoustic energy and in certain cases the only way to correct this phenomenon as well as to control the noise. Finally, some special diffusers have been used as well in the class rooms to see how they impact on the reverberation time and their acoustics.
