"Speech intelligibility in rooms is lowered by its reverberation time higher than 2s with or without sound reinforcement. This is given by the sound energy behaviour in closed spaces. This work is focused on design of sound reinforcement chain in acoustical uncertain highly reverberant spaces. Sound system designs for such spaces are based on usage of loudspeakers with controllable directivity pattern. Principle of exact focused beam of sound energy eliminates unwanted reflections in reverberant spaces. Successive applied philosophy leads to development of compact strategy of design and simulation including requirements for each part of the sound system. Achieved parameters are then measured using rules of developed strategy and compared with required values for intelligibility index."@en . "1"^^ .
