This work presents the results of an investigation on a shading system model, in scale 1:1, carried out in a semi-anechoic chamber. The intention of this study was to analyse the changes in SPL given by the presence of the louvres, both on the façade plane (simulated by the floor of the chamber) and at 2 m from it. Measurements were performed using three different sound source positions and three tilt angles of the louvres. The acoustic behaviour of the system was evaluated with various configurations using louvres without and with sound absorptive material attached to their lower sides. The measurements highlighted an increase in SPL over the “façade” when the standard louvres are installed, while the sound absorptive louvres give an evident SPL reduction on the façade plane and at 2 m from it.

Abstract

This work presents the results of an investigation on a shading system model, in scale 1:1, carried out in a semi-anechoic chamber. The intention of this study was to analyse the changes in SPL given by the presence of the louvres, both on the façade plane (simulated by the floor of the chamber) and at 2 m from it. Measurements were performed using three different sound source positions and three tilt angles of the louvres. The acoustic behaviour of the system was evaluated with various configurations using louvres without and with sound absorptive material attached to their lower sides. The measurements highlighted an increase in SPL over the “façade” when the standard louvres are installed, while the sound absorptive louvres give an evident SPL reduction on the façade plane and at 2 m from it.
