RESUMO

A historical virtual acoustical reconstruction was developed in five movie theaters designed by the architect Rino Levi from 1936 to 1941, in the cities of São Paulo and Recife, by means of computer simulations. Such approach was chosen because these movie theatres have been demised or are now used with different purposes. Rino Levi is recognized as one of the Brazilian greatest architects, and the present work shows that he was perhaps the first to introduce the scientific results of Sabine in the design of acoustical sensitive rooms. By means of the original drawings and reports published by Rino Levi and others, geometric models have been created to carry out the computer simulations. From these models, Reverberation Times and Early Decay Times were obtained, and maps of speech intelligibility parameters such as C50 and RaSTI throughout the audiences have been generated. These allowed the evaluation of the acoustical results that would have been achieved by Rino Levi in these cinemas. Although the approaches employed by Rino Levi was considered innovative at that time, it is shown that some of his solutions, particularly those related to the shapes of the internal surfaces and structures, may be questioned by the present day knowledge. It is shown that Cine-Ufa Palace, the first movie theater designed by Rino Levi, supposedly presented the best acoustic performance among the movie theatres that have been simulated, whereas the adopted solutions to other cinemas, such as Cine Universe and Cine Piratininga, may have contributed to unsatisfactory acoustical results. Finally, regardless of the criticisms that can now be made to his approaches in the acoustical design of rooms, the acoustical reconstruction of the movie theaters designed by Rino Levi was significant, because it has been possible to get acquainted with his views of architecture, which had been based on technical and scientific principles, emphasizing a project reasoning that reveals the clarity of his solutions.
