AB  - This paper addresses prediction techniques for evaluating the consequences of adding a grille assembly onto a loudspeaker. Numerical modeling is applied in order to assess the acoustical effects imposed on the loudspeaker sub-system defined as a loudspeaker, interface, and grille. Investigations are performed in a virtual infinite baffle scenario under semi-anechoic conditions, where various modeling aspects are included in the studies. The predictions are shown to accurately reproduce the prominent features of the sub-system when compared with experimental data. The paper highlights the intricacies of both measurement and correct modeling of the geometry of the parts and their acoustic properties – particularly at higher audio frequencies.
