Experimental and Numerical Investigation of Acoustic Performance for Full-Sized SPS
The sound insulation of a sandwich plate system (SPS) was measured by the sound pressure method in fixed support boundary conditions and reverberation sound field. The results were compared with those obtained using the finite element method. The sound insulation curves obtained via experiments and...

| description | The sound insulation of a sandwich plate system (SPS) was measured by the sound pressure method in fixed support boundary conditions and reverberation sound field. The results were compared with those obtained using the finite element method. The sound insulation curves obtained via experiments and numerical simulation were observed to be in agreement. This indicates that the numerical simulation method can effectively reflect the sound insulation performance of the structure. In addition, the influence of different parameters on the sound insulation performance of the structure was evaluated using the finite element method, and the weight of each parameter in the influence of sound insulation was ranked by applying the function of “fsrftest” in the software MATLAB. It was found that in the low-frequency domain, the length-to-width ratio of the SPS had the most significant effect on the sound insulation performance of the structure, and the mass ratio of the panel to core exerted the least influence on it. Furthermore, in the medium- and high-frequency domain, the main factors affecting the sound insulation were different in the different frequency ranges, and the frequency range should be considered during the design of the structure. The results can provide technical support for the analysis of the sound insulation performance of SPSs. |
