Abstract
In this paper, an integrated analysis model for evaluating the underwater acoustic performance of the multilayered acoustic coatings containing visco-elastic composite layers with hollow glass microspheres is described. The model uses the effective medium theory considering the acoustic scattering and resonance effects of the inclusions. Also, the model incorporates the compressive deformation mechanism associated with hydrostatic pressure. The technique developed in this work was used as the acoustic layer design and performance analysis tools for the practical hull coatings and acoustic baffles in Korean next generation submarines.
Key Words: Multi-layered Acoustic Coatings, Visco-Elastic Composite, Hollow Glass Microspheres, Effective Medium Theory, Underwater Acoustic Performance, Hydrostatic Pressure
