The usual assumption made in sound ray tracing is that the beam pattern will be conic. Approximation of the actual beam pattern using a conic beam is a way to simplify the maths. At the same time, it reinforces what is a false view, namely that side lobes have no effect on the detection capabilities of hydroacoustic systems. The article presents a short description of the sound ray density method which apart from eliminating the problem of computing field intensity in caustics area also enables the inclusion of actual beam patterns of ultrasound transducers. Further in the article, several examples are given of field intensity distribution generated by real transducers. The effect of non-homogeneous media on the distortion of the beam pattern is discussed, too.
