Improvement of Acoustical Properties of Multipurpose Hall

In this paper acoustical measurements in one hall that was originally designed for multipurpose use were investigated. In reality, it was shown that this hall is mainly used for opera and concerts. Since both, the performers and audience, have been dissatisfied with acoustical quality of hall, our target was to define existing state and define cause of objections, i.e. drawbacks. Regarding multipurpose use, measurements were done on all characteristical source and receiver points in hall, for each individual purpose. Besides this, all measurements were done in hall with and without audience in it. The obtained results were analyzed. Upon this analysis, evaluation of present acoustical properties, as well as defining of demands and actions for necessary improvements, for most frequently use were made.
