A useful index for evaluating the two psychological responses to the audio signal and noise and the listening score is first discussed in the case of listening to audio signal under the existing of meaningless steady noise. Hereupon, the mutual relationship between the power spectral level of audio signal and that of external noise is reflected in the above evaluation index. Then, an estimation and/or prediction problems of the two psychological impressions and the listening score of monosyllable audio signal are considered. The predicted values of the psychological impressions and listening score are compared with the experimental data. The observed results are good agreement with the predicted values.
