New ultrasonic measuring techniques use information from local distribution of reflected waves gained with arrays. As they are taking the wave behavior of sound into account, simple geometric models are not sufficient to understand the dependence between quantities being measured directly and these quantities being of interest, like sound velocity in media or the geometry of a specimen. To get this understanding, sound field simulations are necessary which allow to derive evaluation algorithm and to qualify measuring results. To reduce the calculation-effort for axial symmetric problems this contribution presents a new approach to calculate the sound field of a ring-like source. The results are proved by comparing them with the sound field of a disc shaped source.
