混响时间

最初在设计中确定混响时间的方法是利用W·C·赛宾在本世纪初提出的计算公式。

The original method to confirm reverberation time in designs is to use computational formula W . C. Sabin put forward in early century .

评价厅堂音质的混响时间T60和计算公式是上世纪初W·C·赛宾教授（WCSabie）提出来的，在此以后，混响时间一直是室内声学中的一个最重要、最稳定的指标。

Reverberation time T ( 60 ) and the calculation formula used to evaluate the hall timbre were advanced by professor W. C. Sabie last century .

文中以一安装有理想指向性扬声器的矩形房间为例，计算房间的混响时间和各位置处的RASTI。

Loudspeaker with ideal directivity characteristics was considered . Reverberation time and RASTI at different positions in time of a room has a limitation value .

通过理论和实测对用混响时间T10或T20估计衰减曲线早期的衰减速率所产生的误差进行了分析。

The errors are analyzed in theory and with the measurements when using T_ 10 or T_ 20 to evaluate the decay rate of the initial of the energy decay curve .

日本东京新国家歌剧院（NNT歌剧院）容座1810，容积14500m3，（大幕开启时的）满场混响时间1.5s。

The New National Theatre opera house ( NNT opera house ) seats 1810 , its volume is 14500 m3 , and its reverberation time , with audience , is 1.5 s ( proscenium curtain open ) .

模型和实物的对比结果：满场的混响时间除250Hz的差别较大外（约20%），其余频率比较接近（差别少于10%）；反射声图形是相似的；

The results of model compare with actual hall : except 250 Hz ( difference about 20 % ), the reverberation time ( occupied ) at various frequency were close ( difference less than 10 % );
