The present study studies the problems of impact noise and its isolation, through on-site experimentation, and evaluates the criteria of standard 15575-3- (2013) "Housing constructions - Performance", floors. The method is part of a single case study, the Itacolomi residential building, designed by architect Álvaro Puntoni and team, located in São Paulo. In general, in Brazil there is a lack of quality in construction, due to the poor performance of the materials, as well as the lack of compatibility between design and execution. The relevance of this research is due to the problems generated by impact noises in multi-floor residential buildings, caused by factors such as: direct impact on people walking, furniture drag; Vibration of washing machines, etc. These problems are potentiated by the propagation of the vibrations of the structures due to the reduced thickness of the slabs; Of the type of finishing material; Of the form of connections between the structure and its components. The discussion integrates the questions of architectural design, evaluating how the space available in multifamily buildings that can soften the perception of generated noise impact. The importance of the composition of floating floors is also analyzed in this research as one of the ways to solve these problems by insulation of the structure and components with soft and resilient materials. The research highlights the importance of the continuity of this study in the architectural design in order to alleviate the problems of impact noise in residential buildings. These materials and compositions can provide quality and performance. It is observed that the performance norm was structured for the production of social housing, the research concludes that it still needs to undergo a revision because in terms of impact noise allows very high limits compared to international standards impairing the sound quality of the building.
