| dc.description.abstract | Com o passar do tempo, a exigĆŖncia sobre as construƧƵes foi se tornando cada vez maior no quesito da economia, conforto, desempenho, entre outros. Ć neste contexto que a acĆŗstica Ć© inserida como uma necessidade a ser atendida pelas construƧƵes. Esta deve atender a diversos parĆ¢metros para que seja considerada como satisfatĆ³ria, sendo o tempo de reverberaĆ§Ć£o ā objeto de estudo deste trabalho ā um deles. O tempo de reverberaĆ§Ć£o estĆ” diretamente ligado ao entendimento das palavras dentro de um compartimento, ou seja, para que os ouvintes possam entender o locutor claramente, Ć© necessĆ”rio que o tempo de reverberaĆ§Ć£o seja adequado. O ISEP ā Instituto Superior de Engenharia do Porto ā como instituiĆ§Ć£o de ensino demanda de ambientes que contemplem um tempo de reverberaĆ§Ć£o adequado para que a transmissĆ£o de toda a informaĆ§Ć£o seja eficiente. Por isso, este trabalho tem por objetivo analisar o tempo de reverberaĆ§Ć£o das salas do ISEP, comparando os valores ensaiados com os teĆ³ricos, observar a influĆŖncia de variĆ”veis cotidianas e sugerir possĆveis melhorias para algumas salas. A fĆ³rmula utilizada foi a de Sabine, pois as salas se enquadrarem dentro de seus parĆ¢metros de aplicaĆ§Ć£o, e foram ensaiadas sete salas, sendo dois auditĆ³rios, uma sala de reuniƵes e quatro salas de aula, com o auxĆlio dos equipamentos BrĆ¼el & Kjaer. As variĆ”veis analisadas foram as janelas, os estores, os blackouts e a presenƧa de pessoas. Os resultados apresentados demonstram que a presenƧa de pessoas Ć© a variĆ”vel que, dentro daquelas estudadas, mais diminui o tempo de reverberaĆ§Ć£o e que nenhuma das salas abordadas se enquadram dentro da legislaĆ§Ć£o estudada, sendo necessĆ”ria a reforma das mesmas que pode contar com o uso de cadeiras de assento estofado e painĆ©is perfurados. | pt_PT |
| dc.description.abstract | Over time, the demand on construction has been increasing in the economy, comfort, performance, among other aspects. Acoustics is inserted in this context as a necessity to be achieved by the constructions. This must comply with several parameters to be considered as satisfactory, being the reverberation time - object of study of this work - one of them. The reverberation time is directly linked to the understanding of the words within a compartment, in other words, to the listeners understand the speaker clearly it is necessary an adequate reverberation time. The ISEP - Instituto Superior de Engenharia do Porto - as an educational institution demands environments that contemplate a suitable reverberation time so that the transmission of all information is efficient. Therefore, this paper has the objective of analyzing the reverberation time of the ISEP rooms, comparing the values tested with the theoreticians, observing the influence of daily variables and suggest possible improvements for these rooms. To perform this work was used Sabineās formula, since the rooms fit within their application parameters, and seven rooms were tested, being two auditoriums, a meeting room and four classrooms, with the help of BrĆ¼el & Kjaer equipment. The analyzed variables were the windows, the blinds, the blackouts and the presence of people. The results show that the presence of people is the variable that, among those studied, decreases the reverberation time. It was also noticed that none of the rooms comply with the legislation studied, being necessary the reform of them what can be done using upholstered seat chairs and perforated panels. | pt_PT |
