Subjective and objective evaluations of rooms for music

Abstract

A dedicated, computer-based analysis system was developed to perform a complete set of acoustical measurements of recent interest in full-size rooms and in scale models of rooms. The measurements included reverberation time, early reverberation time, loudness, early to late temporal energy ratios, lateral energy fractions, interaural cross correlation, and speech transmission index among others. Measurements were made at multiple locations in ten large concert halls. Groups of listeners evaluated live music performances at three locations in each of the rooms using a seven point semantic differential rating scale. Correlation analysis and statistical modeling identified significant relationships among the qualities of the music in the room rated by the listeners with the physical measurements made in the rooms. Variations of subjective qualities were identified among the different rooms and within each of the rooms as well. The subjective qualities that contributed to overall acoustical impression were also identified. [Work supported by NSF.]

Relationships between subjective and objective acoustical measures in churches

“…This confirms the ideas presented by Chiang 4,5 . The relationship Overall Impression/EDT (R 2 = 0.74) also confirms a similar consideration of this pair of parameters by Cervone 3 .…”

Relationships between Subjective and Objective Acoustical Measures in Churches

“…The summary of the architectural styles of the churches are presented in Table 2. For more uniformity of the sample, only churches with a room volume of less than 19000 m 3 were selected for the study.…”
