CREATING A MODEL OF A SPATIAL SOUND IMAGE (ON THE EXAMPLE OF A CONCERT HALL)
Abstract
This article is devoted to the method of computer simulations acoustic environments and creating a spatial sound image model for assessing the acoustic properties of existing and project concert halls.
An operating concert hall was chosen to create the model. During the sound of music, the acoustics of concert halls have a direct impact on the formation of the spatial auditory image. Architectural features, interior, decoration form a sound field in the closed environment of the concert hall during the sound of music. The acoustic characteristics of concert halls are divided into objective and subjective. Objective determine the acoustic properties of concert halls, subjective – subject to the psychoacoustic laws of human perception of sound vibrations.
Scientific and technological progress affects the active introduction of new technologies. The methods of modeling are considered and the method of computer simulation of their acoustic environment is selected. It is one of the promising areas at the present stage of computer simulation of indoor acoustics. It can be used to assess the acoustic properties of existing concert halls and design. With the help of specialized software, it is possible to simulate the acoustic environment of the concert hall. The software has the ability to replicate the shape, building materials, interior and decoration of the sample concert hall. To compare the acoustic properties of the model and the current concert hall, the sound of the musical material is taken. In this case, use a recording of a piece of music, preferably from the classical repertoire, which sounded in an exemplary concert hall and compare its sound with the sound of the same work in the acoustic environment of the model.
A method of subjective assessment of the sound of musical material using weighty criteria of the established sample for aesthetic assessment of the modeling results is proposed. Aesthetic evaluation of the sound of musical material based on the subjective perception of music by human.
Having such a technique, you can model the acoustics of existing and project concert halls and give recommendations for its improvement.
Research methodology is determined by methods: analytical – in the study of scientific literature; theoretical – to define specific terminology, describe the phenomena that occur during the research, the parameters by which subjective assessment; empirical – when listening audio with expert evaluation of the results; comparative – in the process of comparing research results; methods of analysis and synthesis – to process research results.
The result of the research. The article proposes one of the methods of creating a spatial sound image by modeling the acoustic environment. The analysis of the results is based on an aesthetic comparison of audio examples that sound in the concert hall and its model, which is based on the subjective perception of the sound of musical material.
Modeling at this stage can be considered a promising area of acoustic research with which you can predict the sound of music in the design concert halls.
Scientific Novelty – is an attempt to propose a method of aesthetic evaluation of the acoustic properties of existing and design concert halls by modeling their acoustic environment.
The practical significance. Computer simulations is significant step in modeling acoustic environments. So, this methodology application can be recommended in scientific research.
