Abstract: This paper presents an empirically-based grey-box approach toward estimating the sound insulation of a double-skin façade (DSF) with openings for natural ventilation. A manageable number of input variables pertaining to DSF's geometric and material attributes facilitate the computation of frequency-dependent and weighted sound reduction index values of the DSF. The resulting functionality can aid designers and engineers toward developing and accessing various configurational options regarding DSFs with combined ventilation effectiveness and acoustical protection.
