The study of the acoustics of enclosed spaces was developed to identify the conditions where the sound, music or speech, could spread optimally and be clearly perceived by the listeners. In ancient times, this study was treated empirically for the same purpose and only the late nineteenth century was born as science to work by an American physicist named Wallace Clement Sabine (1868 – 1919), dedicated to the deepening of the phenomena reverberation and sound absorption applied to the design and the acoustic correction of theaters and concert halls.
The author, in reference to these phenomena, describes his own project proposal acoustic correction of a multipurpose room to adapt, with a first operation, the acoustic parameters of a conference room and then, in a second operation, in those of a room for listening to classic music.
For a better understanding of the topics, the proposal is preceded by some fundamental notions of acoustic starting from the combination of sound physics, the phenomenon of his generation and its propagation, and then make a mention of the environmental acoustics and architectural history. Is then introduced into the vast set of problems related to the behavior of sound in enclosed spaces, ie places for listening to music, the great halls and theaters, describing the theo-ries, the physical models, the conceptual tools available to understand the reality of the acoustic field and the considerations of the different parameters to be taken into account in the acoustic design / correction of closed spaces.
