摘  要:厅堂音质设计中响度是最基本的评价参量之一,目前通常采用相对强感(又称强度因子)G(dB)作为评价响度的参量。吴硕贤等人(2001)则认为这一参量不足以说明听众的真实感受,提出用乐队齐奏强音标志段(forte)的平均声压级LpF作为评价音乐厅内响度的新物理指标为好,並可用Barron的简单修正公式进行估算厅内各处LpF的分布。从实用意义、客观测定、音质设计预估等方面,对此新评价参量作出剖析和评论,以说明其存在的问题和不可行性。Loudness is an important criterion for assessing the acoustical quality of hall. A criterion parameter known as strength G (dB) has been widely used for loudness evaluation in the acoustical design of auditoriums. But for seeking a so called authentic loudness criterion in a concert hall, Wu et al. (2001) suggested that the mean forte sound pressure level of tutti-sound, LpF (dB) could be a new criterion to evaluate the perceptive loudness of the audience. They also recommended that these LpF values in a hall could be simply predicted by Barron's revised theory. In this paper the author gives some criticisms on that new criterion in practice, and also illustrates that both the measurement procedure and evaluation method as they suggested are not feasible.
