Análise de comportamento acústico de diferentes componentes de vedações verticais

Abstract

The technological innovations caused a pace acceleration at which cities grows, resulting in a great exposure to noise for any inhabitant of urban cities. However, at a certain point, this accelerated pace meant a regression in the acoustic insulation of buildings. In recent years, acoustic quality has been undervalued due to economic factors, and the need to carry out constructions quickly and with economy of resources. So, the acoustic performance had to give way, becoming a forgotten attribute in most of the buildings. Based on these statements, this work seek to analyze some blocks used in the city of Maceió - AL, which were chosen through field research and literature review, with the pretext of comparing the acoustic performance between the blocks and analyzing the values obtained through the normative. The results were obtained at the Laboratory of Structures and Materials (LEMA) of the Technology Center (CTEC) of the Federal University of Alagoas (UFAL), located in Maceió - AL, using plaster blocks, ceramic blocks and concrete blocks. Resulting in values below the minimum performance level, reducing the comfort and well-being of the user, since the Performance Standard serves to guarantee the health and quality of life of the user. With this, it is up to builders to seek innovations that improve the ability of the blocks to retain everyday noise, always seeking to make use of good quality materials and skilled labor.
