This data article comprises collected data to verify a vibro-acoustic coupling model and raw records of optimized results on sectional geometries of two simplified sealing rubber models. The dataset is generated based on both analytical methods and numerical solutions, including Finite Element Simulation and Hybrid Finite Element - Statistic Energy Analysis Simulation. The calculations have been performed through a 2.3GHz PC with Intel Xeon Core E5-2658 v4 and 128 GB RAM in Tongji University. All the results from these data will help researchers and engineers in vibro-acoustic coupling analysis of dual-membrane or combined dual-membrane models with a sine-auxiliary function and advanced understanding of the coupling characteristics. One of the main original contributions is also to share the data sets to give the opportunity to researchers for testing and validating numerical models of the vibro-acoustic coupling problem. In addition, the optimization characteristics of sectional geometries of the sealing rubber models based on a modified simulated annealing algorithm can retain further potential analysis with the data provided. This Data in Brief article is an additional item directly alongside the following paper submitted in the Elsevier journal Applied Acoustics, "Optimal study on sectional geometry of rubber layers and cavities based on the vibro-acoustic coupling model with a sine-auxiliary function" [1], where the detailed interpretation of models and results can be found.
