Numerical Design of Sound-Insulating Material with Combined Cavities of Mixed Sizes
In view of the low-frequency acoustic insulation performance and poor pressure resistance of a single cavity at present, finite element software COMSOL is used to establish an analysis model to calculate the sound transmission loss (TL) and compression performance of the sound-insulating material wi...

| description | In view of the low-frequency acoustic insulation performance and poor pressure resistance of a single cavity at present, finite element software COMSOL is used to establish an analysis model to calculate the sound transmission loss (TL) and compression performance of the sound-insulating material with combined cone cavities. The effectiveness of the numerical method is validated by comparing with the experimental results, and influence of the structural parameters of the cone cavity, the perforation, and the mixed cavity shape on the sound transmission loss is investigated. |
