ANÁLISE COMPARATIVA DAS SIMULAÇÕES COMPUTACIONAIS E MEDIÇÕES EM CAMPO DO REQUISITO DESEMPENHO ACÚSTICO EM VEDAÇÕES VERTICAIS INTERNAS

Abstract

In view of the scenario of increasing search for quality in buildings, meeting the performance standard has been a challenge for builders, designers and suppliers. The losses and, consequently, the costs of adaptations in the post-work are infinitely greater than adaptations that can be implemented during the design phase. The use of computer simulation has been the tool by which it is intended to predict the acoustic behavior that will be found in the measurement on site, thus ensuring the quality required by NBR 15575. This research aims at a comparative analysis of data from computer simulations (SC) and data from field vulnerability (MC) from 14 case studies, in internal vertical sealing systems (SVVI) regarding acoustic performance. 75 SVVI data were analyzed, and the results showed that more than 50% of the SC data were compatible with CM data, with variations in the order of ±2 dB. Removing discrepant data, due to program limitations, this percentage reaches 66%. In general, the results of the comparative analysis point out as positive the use of simulation as an instrument of acoustic prediction, with some limitations, but effective in the search for the acoustic performance of residential buildings.
