Medidas para la obtención del certificado acústico en viviendas de primera construcción y cálculo de la incertidumbre en las medidas

Abstract

In this work, explains and discusses the procedure for obtaining the certificate acoustic in new buildings to achieve the requirements of the sound insulation, according to the following laws and regulations: · UNE en ISO 140-4 and 140-5. · Technical Building Code (DB-HR): protection against noise. · Regulation of protection against noise pollution (Valencia town). In addition, it is also calculated the uncertainty of measurement associated with sound insulation of airborne tests, in which we aim to estimate the quality and reliability of the measurement system used. A theoretical description has to be done first: · Sound insulation. · Current norms to measure `in situ¿ · Uncertainty. Then, a suitable measurement will be done putting into practice these concepts (in particular studying a newly built housing) and thus we will get all the information needed to the right realization of the project. Finally, we evaluate the uncertainty of measurement introduced by the different magnitudes that define assessment contents of airborne sound insulation of from the data obtained from the sound level meter calibration certificate, the manufacturer's instructions and the environmental conditions under which measurements are made.

El objetivo de este proyecto es la evaluación ¿in situ¿ del aislamiento acústico a ruido aéreo, diferencia de niveles estandarizada, Dls, 2m,nT de las fachadas de la promoción de dos viviendas unifamiliares y del aislamiento acústico a ruido aéreo, diferencia de niveles estandarizada DnT, entre las estancias de las viviendas, para posteriormente, calcular la incertidumbre de medida asociada a los ensayos efectuados.
