摘要
Abstract
Based on statistical energy analysis (SEA), the model for high frequency noise prediction of offshore platforms is established. Using the VA One software, the high-frequency noise is predicted in the cases of considering and without considering outfitting materials. Comparing the calculated A-level of sound pressure of the cabin noise with the specification value, the cabins which do not satisfy the noise specification are extracted and treated with noise control measures. In addition, according to the energy input situation and energy transfer path of the cabins with excessive noise, the optimum layout of the damping materials can be determined. Based on the material sound absorption characteristic within different frequency band, multilayer sound-absorbing materials are applied to the cabins to reduce sound pressure level. The thickness and mass of the sound-absorbing materials are optimized by using Sequential Quadratic Programming. The results are verified by mutual comparison of the results of simulations.关键词
