EVALUACIÓN PRÁCTICA DEL AISLAMIENTO ACÚSTICO DE DUCTOS UTILIZADOS PARA LA VENTILACIÓN DE VIVIENDAS

Abstract

This research is a practical evaluation of a “two-way” muffler, designed and built for the acoustical solution of duct ventilation used in energy efficient dwellings. Specifically this evaluation was carried out by lab proves, in which test-mufflers were exposed to white noise levels up to 95 dB(LIN), simulating the muffler mounting condition as placed inside a rigid wall. In this way the required data for measuring the attenuation improvement is obtained.
