A Computationally-Efficient Numerical Model to Characterize the Noise Behavior of Metal-Framed Walls

Metals, 2015
Architects, designers, and engineers are making great efforts to design acoustically-efficient metal-framed walls, minimizing acoustic bridging. Therefore, efficient simulation models to predict the acoustic insulation complying with ISO 10140 are needed
