Este relatório constitui um documento desenvolvido no âmbito da unidade curricular Dissertação, Projeto ou Estágio, DIPRE, do Mestrado em engenharia civil do Instituto Superior de Engenharia do Porto.
Este documento começa por apresentar a empresa de acolhimento do estágio, bem como as atividades desenvolvidas durante o mesmo, com destaque para o acompanhamento e fiscalização de obras, estudos prévios para a reabilitação de uma moradia unifamiliar e projetos de condicionamento acústico.
O tema mais detalhado neste relatório é a acústica de edifícios, onde se pode encontrar a metodologia de cálculo a ser aplicada posteriormente no caso de estudo, nomeadamente o modelo de Sharp, o modelo de Meisser e a lei da massa teórica. Por outro lado, são apresentadas breves noções acerca dos ensaios acústicos, ruído ambiental e o ruído de equipamentos e instalações. Como ferramenta informática, e por forma a poderem ser obtidos valores utilizados em análises comparativas, é abordado o programa de cálculo automático Cypevac III, explicando-se o seu funcionamento e apresentados as tabelas de cálculo em anexos. Para finalizar a abordagem teórica, é apresentada a legislação aplicável à acústica de edifícios, nomeadamente o Regulamento Geral do Ruído e o Regulamento dos Requisitos Acústicos dos Edifícios.
Por último, é feito um caso de estudo relativa à avaliação do desempenho acústico de dois edifícios de habitação unifamiliares geminados, aplicando a metodologia de cálculo apresentada anteriormente. A avaliação está organizada de forma a ser semelhante a um projeto de condicionamento acústico. No fim deste capítulo, é feita uma análise comparativa aos resultados obtidos anteriormente nos dois edifícios.
This report is a document developed within the course thesis, project or internship, DIPRE, the Master of Civil Engineering of the School of Engineering of Porto. This document starts with the host company of the stage, as well as the activities developed during the same, especially the monitoring and supervision of works, previous studies for the rehabilitation of a single family house and acoustic conditioning projects. The most detailed theme in this report is the acoustics of buildings, where you can find the calculation methodology to be applied later in the case study, namely the model of Sharp, the model Meisser and the law of theoretical mass. On the other hand, are brief notions of acoustic testing, environmental noise and the noise of equipment and facilities. As a software tool, and so that it can be obtained values used in comparative analysis, is approached the computer program Cypevac III, explaining the functioning and presented the calculation tables in annexes. Finally the theoretical approach is presented legislation to he acoustics of buildings, including the General Noise Regulations and Regulation of the Acoustic Requirements of Buildings. Finally, it made a case study on the assessment of the acoustic performance of two buildings twinned single-family housing, applying the calculation method presented above. The assessment is organized to be similar to an acoustic conditioning project. At the end of this chapter, there is a comparative analysis of the results obtained previously in two buildings.
