本文提出了一种新的火花放电脉冲声源模型，并通过理论估算和实验获得的输出脉冲波形的比较，验证了该模型的有效性。本文首先描述了脉冲火花放电声源模型和波形方向依赖性的估计方法。在对脉冲声源结构作了简要说明后，将实验获得的脉冲输出波形和指向性图与理论估计的波形和指向性图进行了比较，两者吻合较好。本文提出的模型很好地解释了实验结果。
This paper proposes a new spark discharge pulse sound source model, and validity of the model is examined by comparison between the theoretically estimatedand experimentally obtained output pulse wave forms. This paper describes first the pulse spark discharge sound source model and an estimation method for directional dependency of the wave form. After a brief explanation of the pulse sound source structure, the experimentally obtained output pulse wave forms and directivity patterns are compared with the estimated ones and the good coincidence between them is shown. The model proposed in this paper explains well the experimental results.
