| Title of the article | Study of acoustics of educational premises by the criterion of speech intelligibility |
| Abstract. | Problem statement. The acoustics of the classroom, in particular articulation (speech intelligibility), affects the perception of educational information. Speech intelligibility can be assessed both at the design stage and in-situ indoors, however, the parameters underlying these techniques differ, and therefore the results may differ. The aim of the work is to find the relationship between speech intelligibility in classrooms of various typologies with their architectural parameters. To achieve the goal, the following tasks were solved in the work: – to evaluate speech intelligibility in classrooms using full-scale and computational methods; – to evaluate the convergence of different methods; – to identify the relationship between the various architectural parameters of classrooms and the intelligibility of speech in them. Results. The spread of articulation values in the same room with different listeners can be several tens of percent. The study showed that the human factor (lack of interest in the experiment, distracting and interfering behavior of children, hearing acuity, etc.) can make a much greater contribution to speech intelligibility than the spatial planning and acoustic characteristics of the room. Conclusions. The paper shows that in order to achieve higher values of speech intelligibility in classrooms, preference should be given to more compact rooms with smaller dimensions and fewer seats, which will reduce the distance of listeners from the speaker and minimize the opportunity for listeners to communicate with each other and, as a result, improve information perception. |
