Improvement of Classical Music Sound Conditions by Simulating Changes in Concert Hall Acoustics

Abstract

The purpose of the research is to propose a method of acoustic research of concert halls to improve the classical music sound conditions with the help of innovative computer technologies. The research methodology is as follows: to improve the sound conditions of classical music, a computer simulation method is proposed, which involves the use of specialized software. The method of subjective evaluation through the criteria of the established sample is used to systematize the results of the study. The comparative method was used to analyze the sound of audio materials of the created spatial sound images of the orchestral music sample. The scientific novelty of the research is that it presents a methodology of acoustic research for the environment, in particular concert halls, which arose as a result of changes in the acoustic conditions of classical music. Conclusions. As a result of the experiment, the main goal was achieved – to improve the sound conditions of classical music. The result was achieved by modeling changes in the acoustics of the concert hall. The use of this methodology can be recommended during the research of existing and projected concert halls. In further studies, the use of diffusers with low absorption coefficients in the lower frequency band can be recommended. It should also be noted that interference with the interior of a historic building should be discreet, as this may cause dissatisfaction among the authorities controlling heritage preservation.
