Subjective Evaluation of the Room’s Acoustical Qualities

In this paper subjective testing of room's acoustical qualities were investigated. Testing was made in the same conditions, with the same equipment, in two rooms with same dimensions, but with different acoustical properties. First room (seminar) was very reverberant, that is, not acoustically treated, and the other (studio) was acoustically treated. Many subjective parameters were investigated, and certain were chosen and modified. We derived definitions of the subjective acoustical parameters, and made scale of numerical marks. According to the testing results, room's acoustical qualities were evaluated and testing method was defined and suggested.
