Abstract |
The purpose of this study is to propose a new method for evaluating the sound field of auditoria with incorporation of the measure for listener envelopment(LEV). In this paper, the strength of LEV is ...calculated in existing halls based on the previous results of objective measurements and psychological experiments, and the relation between LEV and the characteristics of late arriving sounds(C80 and directional late energy ratios) is examined. The result shows that significant differences in perceptions of LEV are found in the different seats and its range differs according to the objective properties of the halls. This confirms that the consideration of LEV is important for the evaluation of sound fields.show more
