When an electro-acoustical transducer is electrically supplied, it yields an acoustic field in the propagation medium. The acoustic field knowledge allows us to obtain significant help to transducers design and propagation medium interaction studies. In this paper, it is shown a proposal of classroom work involving the studied contents of physics, mathematic and computing in the introductory lessons of degree course of exact science. It is proposed the discussion about wave interference phenomena, the determination of acoustic field using cylindrical coordinates and the software of the mathematical method applying basic instructions of a computational language. The simulations of some acoustic fields are shown in bi and tri-dimensional graphics and the results are discussed.
