Abstract
Several factors affect the acoustic quality of an environment, and it is up to the designer to know how to control such factors, as depending on the type of environment and the activity to be performed in it, they require specific acoustical treatments. In places that need clear understanding of the word, such as a movie theater, for example, it is essential to control the reverberation time (RT), and isolation beatween internal and external noise. For the object of research, it selected a street movie theater in the city of Belém of Pará, the Olympia cinema, the oldest in operation in the country, being of extreme historical and cultural importance to the state capital. In this context, through experimental measurements and computer simulation with Odeon software, will assess the acoustic performance of the object of study room , based on the great TR found in NBR 12179/92, taking into consideration the enclosure volume , and a proposal for acoustic adaptation by indicating new materials that promote the best acoustic comfort of the environment, which in the case of this research, aims to reduce the room reverberation to meet the standard acoustic treatment enclosures closed.
