混响感的因素分析

Factor Analysis of Reverberation Perception

混响时间是影响混响感的重要因素,但并不是唯一因素。为探讨不同因素对混响感的影响,首先用问卷调查的方法对混响感的影响因素进行了汉语语义调查,根据语意调查结果针对对混响感具有较大影响的几种因素采用尺度估计法设计了一系列主观听感实验,实验结果表明除混响时间外,声压级、频率、感知距离、平均吸声系数和反射声方向等因素也对混响感具有显著影响,除上述因素外,被试者所聆听的声音内容对混响感也会产生不同程度的影响。

The reverberation perception is affected by many attributes although the reverberation time may be the most important. The contribution to the perceived reverberation from different attributes was studied by factor analysis. The semantic meaning of the reverberation is studied with the questionary. The factors to be analyzed in this paper were based on the res.ults. A series of listening tests are carried out to study the relationship between the reverberance and the given factor by the Magnitude Estimation Method. The results shown that besides the reverberation time,the reverberance could also be influenced by the sound pressure level,the frequency,the perceived distance （d/r） , the direction of the reflected sound and also the content in different ways.
