The paper presents a theoretical approach to the problem of modelling of real sound sources or given radiation directivity characteristics. The research concerns only fixed monoharmonic vibrations. The paper presents also the results of experimental concerning the chosen industrial sound sources and the attempts to model these sources by means of a system or substitute sources composed of monopoles. The experimental results can be used for the active sound compensation in the multi-dimensional systems.
