The subject of the research is the architectural and acoustic study of symphonic music halls and buildings. The present research is a type of handbook for these buildings after exploring the basic elements of acoustic architecture and giving some examples of buildings that represent it. Initially, reference will be made to the theory of acoustics and physics, acoustic phenomena and notions necessary to understand the acoustic of buildings. Then the typology of the areas of interest and their key properties are referred to, in order to categorize the halls for each building. Then, some of the most important architectural examples of acoustic and architectural interest will be analyzed. Their analysis will initially be based on their architectural particularities, that is, the spaces they comprise, their shape, their structure, their materials, their relationship to public space and the architectural ideology followed by the architects for their design. The symphonic music room will then be analyzed for each building. It will be determined, their acoustic form, their relationship to the rest of the building, the basic acoustic criteria that acoustics used in their design, and the different additions made, to achieve the perfect acoustic . Finally, they will be compared with each other on the basis of different parameters affecting the acoustics of the sites, in order to arrive at a more general conclusion on the acoustic design of these sites. The comparison will be complemented by the architectural ideology and design of the buildings.
