Improvement of sound insulation on the modular housing

Abstract

The modular construction method is an architectural technique in which buildings are produced in factories and then assembled on construction sites to complete the construction process. This method has two main advantages. First, since the construction takes place in factories, it can reduce construction waste. Second, it can shorten the construction period on the site. So there is considerable interest in using the modular construction method for the construction of residential buildings. In this study, the purpose of the modular construction method in the case of residential buildings is to improve the indoor sound insulation. For this purpose, first, the sound insulation performance of the walls and floor structures has been predicted through simulations at the design stage. Second, the sound insulation performance of the walls and floor structures has been measured using mock-ups in the factory and compared with the simulation results. Third, the sound insulation performance of the walls and floor structures in the actual completed building has been measured and compared with the performance of the simulations and mock-ups. As a result, we have compared the performance of modular construction from the design stage to the completion of the building. Through this process, we have presented procedures for improving the sound insulation performance of the building and quality management, from the design phase to the post-construction stage.
