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.
