We are happy to share our latest research paper, where we explore innovative solutions for challenging vibroacoustic problems using the time-domain nodal discontinuous Galerkin (DG) method. This study addresses two key problems:
– Impact Sound Radiation: We examine the sound radiation from a rectangular floor into a cuboid room, assessing normalized sound pressure and comparing it with results from the modal expansion method.
– Sound Transmission: We analyze sound transmission between two rooms, considering both direct and flanking contributions. Our pressure transfer function results are validated against the finite element method (FEM).
Key highlights of our research include:
– Advanced Modelling: The structures are modeled as 3D solids governed by linear elasticity equations, with sound propagation governed by linear acoustic equations.
– Innovative Techniques: We detail the use of upwind numerical fluxes in DG for both governing equations and present robust coupling conditions.
– Promising Results: Our findings demonstrate excellent agreement with established methods (modal expansion and FEM), with only minor discrepancies in resonance frequencies and magnitude.
This research not only advances our understanding of vibroacoustic phenomena but also paves the way for more accurate and efficient simulations in engineering applications.
