Sažetak
This paper presents the research results obtained by measuring and assessment of professional sound control room. In this process all the features that these rooms have are taken into consideration and that is the fact that here the sound is reproduced through high quality professional equipment, and that listening area is only a small, exactly given place for optimal listening. The optimal sound control room must give completely clear perception of reproduced sound with all features, and the space as itself may not enter or change the characteristics of the reproduced sound. Also, the acoustic characteristics of the original recording room should be unchanged. This is obtained by creating very high quality sound control room, which includes designing, implementing and ultimately control measuring and testing. Statistical Conjoint Analisys methods (CA) is statistical tool that shows which of the real, objective parameters of a test system has the greatest impact on the final subjective assessment or on the subjective decision of the respondents to the assessment of the system quality. In this work, a Conjoint Analisys method is used to obtain estimates of the impact of objective parameters of acoustic quality of the room on the subjective assessment of the reverberation time of the professional sound control room. Thereby, the use of modern statistical method (CA) shows dependence of one subjective parameter on more objective parameters, which is much closer to the real situation. Realistically, all ratings are subject to some extent dependence on more objective parameters.
