摘要在Neumann边界条件下基于近场声全息原理(NAH)重构了两端封闭的有限长圆柱壳体内部声场,计算出的结果与基于模态叠加法构建的内部声场进行比较,证明了重构方法的正确性,然后分别讨论了激励频率和全息面选择对NAH重构声场精度的影响以及重构面上不同位置的重构效果。 Under the Neumann boundary condition, the interior sound field of a cylindrical cavity with endcaps is reconstructed, based on nearfield acoustic holography （NAH）. By comparing the sound field calculated by NAH with that calculated by the modal superposition approach, respective effects of the excited frequency, location of the holographic surface and location of the observation point on the reconstructing surface are investigated on the sound field reconstruction.
