| Description | Journal: Journal of Physics: Conference Series The multi-row perforated concrete wallboard with built-in sound insulation materials studied in this paper is a new type of lightweight sound insulation wall. With reference to the authorized utility model wall, this work performs sound isolation tests on walls with different internal structural parameters cast on multiple sections, using the experimental method of sound insulation room. Based on the experiment, COMSOL numerical simulation software is used to establish a sound-solid multiphysics model to achieve the numerical solution. Three kinds of changing parameters are studied with respect to the effect of the sound transmission on the wall panel. The optimal cross-section combination structure discovered is a foam concrete wall panel with a 15mm thick sound insulation layer, multiple rows of 30 mm diameter holes and a large flow resistance. |
