摘要
用ODEON软件模拟了4个厅堂的声场,得到了每个厅堂内3个受声点的语言传输指数STI的模拟值;同时通过Peutz公式预测了这些受声点的快速语言传输指数RASTI预测值。比较模拟值与预测值发现:模拟值和预测值的线性相关系数较高,但两者并不一致。
The ODEON software is employed to calculate the STI values of 3 receivers in each of 4 selected rooms, and Peutz formula is used to predicte the RASTI values of these receivers. The comparison between these two sets of values shows that the predicted values by Peutz and simulated values by ODEON are highly correlated but not equal.
