Abstract
The subject of the report is the methodology of carrying out an examination of the application for the purpose of establishing the optimal acoustic minds in the prevalence of attribution. The goal is to improve the quality of all stages of acoustic examination, taking into account the premises for which there are special requirements for the quality of the transmitted content or for which there are features in the formation of the sound field. Such a sequence of stages requires the solution of several tasks: determining the conditions for conducting research, taking into account the specifics of the premises and content; selection of hardware and software complex for research; determination of informative criteria for assessing the acoustics of a room, taking into account all its features; processing and analysis of the results obtained. The application of this approach to the stages of acoustic examination was considered on the example of a conference room, for which there were requirements for high quality speech content, a sound reinforcement system was already used in the hall, and there were features in the formation of a sound field. The authors in the article describe the solutions to all the tasks for the investigated room. The results obtained made it possible to analyze the objective characteristics of the sound field and identify the reasons for the low quality of speech content transmission not only in the acoustic calculation, but when using the existing sound reinforcement systems (electroacoustic calculation). Conclusions. The proposed sequence of the stages of acoustic examination makes it possible to identify "problem" places in the formation of the sound field and / or to determine possible solutions even before the stages of checking existing architectural and construction solutions and the development of technical specifications for the construction of enclosing surfaces and measures to create optimal acoustic conditions.
