Enhanced sound insulation in double wall structures via MAMs: An RBF-based optimisation approach
Materials & DesignDouble walls are widely used as they provide a higher level of sound insulation without compromising on mass. However, due to the coupling resonance between the structure and the cavity, additional sound insulation valleys occur, which are not beneficial
