The just noticeable difference (JND) of the reverberance was tested using the constant-stimulus, method. Some factors that may influence the tested results are analyzed to validate the experimental data. The test materials are the Chinese instrumental music. Three subjects groups were tested, including the audio technician group, the students from audio engineering department and a group of postgraduates majoring in acoustics. It is found that the value of JND of reverberance is about 25%. The difference possibly caused by the professional training and experience of different subjects groups is noticeable, but the difference caused by different music motifs is insignificant. 相似文献
