The invention can be efficiently used for intensively learning different disciplines, including foreign languages, and for forming and automating operational skills of professionals in different field of activity. It makes it possible to obtain a technical result and a high-quality intensive training. The use of a training aid is developed according to a synergetic theory in the form of a synergetic training device and makes it possible to provide a synergetic variant of intensive training. The synergetic training device is embodied in a dynamic technical device consisting of several soundproof booths which comprise training facilities and technical means using a sensor system. The synergetic training device makes it possible to intensify and simultaneously diversify the training activity of trainees, to develop an integrated-in-groups training method according to a ‘assistant-students’ system consisting in simultaneously training mini-divisions under the guidance of a large group of assistants, including technical assistants. The possibility of simultaneously taking into account all levels of training provides the method with a multi-level character, while the possibility of taking into account the peculiarities of the students guarantees the high antropological attitude thereof.
