Determinação de método de cálculo das incertezas estatísticas dos parâmetros de entrada do item 3.2 da norma ISO 10140-3

Abstract

Among the most diverse problems that can interfere with human health, there is noise exposure. By observing the amount of research from the most diverse areas evidencing this theme, its interdisciplinary nature becomes evident. The present work aims to determine the parameter calculation of statistical uncertainties for the input parameters of item 3.2 of ISO 10140-3, from acoustic tests experimental data with screeds made of recyclable materials, in addition to the verification of the noise passing through these constructive elements. The previously obtained data will be analyzed using spreadsheets and statistical calculation methodology. Different specimens of non-conventional materials and only one type of floor coating were analyzed, the results show that the methodology is credible because when applied it results in data similar to international standard ISO 12999 standard stipulations.
