摘要
利用Odeon仿真软件,对55个不同听音位置,采用3种方法计算语言传输指数(SpeechTransmissionIndex,简称STI),并进行比较分析.结果表明,应用早期衰变时间(EarlyDecayTime,简称EDT)比应用混响时间(T30)计算语言传输指数较为可靠.
The speech transmission index (STI) is obtained from architecture acoustic design software Odeon for 55 listening position with three methods. The results are compared and analyzed. It is proved that STI obtained from early decay time (EDT) is more reliable than that from reverberation time (T_(30)).
