| Research Abstract |
A conceptual model for manufacturing the new type of soundproofing ventilation grille unit is presented. The central problem is in designing the shape and dimension of this unit and the placement of these input and output opening in such a way as to maximize ventilation as well as preventing outside noise from entering the home. In this work, a method to predict the insertion-loss of ventilation grille unit is proposed by solving the wave equation, considering the resonance frequencies of higher-order mode.
