摘要

As the acoustics of the two of three halls of Slovenian National Theatre inMaribor proved inadequate, its management has asked for an expertlyanalysis of the existing acoustical status. The objective part of it comprisedinvestigations of: useful and detrimental reflections, reverberation time curves,direct-to-reflected energy ratios, clarity values and ALcons and RASTI values.Subjective investigation included syllabic intelligibility tests and qualifiedlisteners’ evaluation. Subsequent analysis gave designer all the necessaryparameters for reconstruction.
