摘要
厅堂响度是厅堂音质的重要参量。基于厅堂脉冲响应能量的强度因子G作为厅堂响度客观评价参量,由于未考虑人耳的听觉特性与主观响度不一致。基于Moore时变响度模型计算了厅堂脉冲响应的响度,以厅堂脉冲响应的最大响度值作为厅堂响度参量,并分析了其在实际厅堂中的分布。
Loudness is one of the most important acoustical attributes. Sound strength G based on sound energy of impulse response leads to discrepancy in loudness assessment, due to not taking into account auditory characteristics. Loudness based on impulse response is derived using time vary loudness model, and the maximum loudness value is adopted as loudness factor to predict loudness in halls. The distribution ofloudness factor and sound strength in a hall arecalculated and analyzed.
