[Abstract]We examined the effects of the levels and the spectral characteristics of noise added to the original music pieces on the evaluation of the "goodness of hearing" and the EEG fluctuation at the time of listening to the sounds, in two experiments. In Experiment I, 15 evaluation sounds consisting of 3 original music pieces and their sounds to which noise was mixed either with five S / N ratio, and, in Experiment II, 12 evaluation sounds consisting of 3 originals and their sounds with brown noise, pink noise, or white noise added were used. It was shown that as the level of mixed noise increased, or as the energy in the high frequency range of mixed noise increased, the "goodness of hearing" evaluation decreased, the %α wave or the α/β decreased, and the %β increased, but only in a group listening to one original music pieces and its tokens with noise. The other groups listening to different originals and their tokens with noise showed that values of psychological evaluation correlated with %α or α/β positively, or with %β negatively.
