IMPROVING THE SOUND CONDITIONS OF MUSICAL GROUPS IN CONCERT HALLS OF HISTORICAL AND RELIGIOUS BUILDINGS (ON THE EXAMPLE OF THE HOUSE OF ORGAN AND CHAMBER MUSIC OF THE CITY OF LVIV)

Abstract

The aim of the paper is to establish the improvement of the sound conditions of musical groups by applying the complex methodology of acoustic research of concert halls that underwent reconstruction during historical periods.
Research methodology. In this article, the research is based on the study of the achievements of acoustic scientists, as well as the following methods: analytical – in the study of scientific literature; theoretical – to define special terminology,
description of phenomena that take place during research, parameters according to which evaluation is carried out; empirical – when listening to musical groups in a concert hall with subsequent expert evaluation of the results. Comparative – in the process of comparing research results; methods of analysis and synthesis – for processing the research results, as well as the interview method – for obtaining information from musicians and active listeners.
Results. As a result of the study of the acoustic properties of the concert hall before and after the reconstruction, we can summarize: the sound of musical groups has changed for the better, but the expert group is inclined to the opinion that the sound of fast, dynamic music is less desirable in this concert hall. Instead, the hall is more suitable for works of sacred music that are performed at more moderate tempos.
Subjective assessment of acoustic quality is mainly confirmed by objective acoustic parameters, so the application of the proposed research methodology for concert halls that have undergone reconstruction can be considered justified. It
received a particularly accurate confirmation (almost complete) among specialists. An oral survey, which was conducted among amateurs of symphonic music, showed the one-sidedness of their assessments. They ranged from «good» to
«excellent» and therefore less accurate.
Therefore, the evaluation of the sound of musical groups by acoustic experts, sound engineers, composers, conductors, musicians, music critics and regular concertgoers (specialists) in most cases corresponds to real acoustic conditions.
Novelty. Consists in an attempt to propose an original research methodology, which is based on the method of full acoustic research, to concert halls of historical and religious buildings that have undergone reconstruction.
The practical significance. This original methodology can be proposed for the research of all concert halls that have undergone reconstruction.
