In this paper, a new method which is SHIEF ( Synthetic Helmholtz Integral Equation Formulation) for calculating acoustic field radiated by an arbitrary radiator in the unbounded space is presented. 提出了一种计算无界声媒质空间中任意形状辐射体辐射声场的新方法&综合Helmholtz积分公式法(SyntheticHelmholtzIntegralEquationFormulation,SHIEF)。
This method is based on the idea that the acoustic field of a complex radiator can be reconstructed from the superposition of fields generated by an array of simple sources enclosed within the radiation. 波叠加法的思想是:任意复杂结构的辐射声场可以由置于辐射体内部的一系列简单源产生的声场叠加重构而成。
Near-field acoustic holography is a very important technology in acoustic researching, which can reconstruct and predict acoustic quantities in the whole 3-D field by recording the sound pressure in the near-field of radiator. 近场声全息是声学研究中的一种极其重要的方法,通过在辐射体的近场测量声压数据可以重建和预测出整个三维空间声场的声学量。
