This research considers the way in which a room accomodates concerts. The role of a concert hall is as important as the quality of the concert itself, because it concerns the fact that either will upgradeor downgrade a concert. Every room, then, must have some specific features in order to have the proper acoustics, depending on the purpose to be accomplished.

Firstly, there is described the phenomenon of sound and its behavior in open and closed spaces and is given an explanation about objective and subjective criteria, according to which the acoustics of a concert hall are evaluated. Furthermore, there is referred the procedure by which a sound room is considered, as, also, main principles of designing a concert hall, the conditions of setting them up and ways in which possible failures can be avoided. Additionally, there is given the historical development of concert halls, together with examples of acoustics solution, depending on the experience and knowledge of each period, while the acoustics of impressive buildings in modern architecture are examined and the way in which architecture of these rooms is affected by the acoustic requirements. Finally, there are given conclusions and views generated through this research.

To conclude, the aim of the research is how these two concepts, music and architecture, are combined and to prove that the acoustic solution as main principle of architectural composition can be the absolute prerequisite in order a whole building organization to be succesful. Therefore, the correct acoustic design contributes to erect exceptional buildings, but also to the general development of architecure.
