 note = {[Abstract] The purpose of this study is to explore the relationship of acoustic features of sound, listener's impressions to them, and their EEG patterns. The two factors, named "goodness of sounds" and "fineness of sounds", were extracted from a factor analysis for the impressions of transient sounds and continuous music sounds by the Semantic Differential method. Using psychological scales based on these two factors, subjective evaluations of original music sounds, down-sampled sounds and noise-added sounds of originals were obtained, and simultaneously EEG_s were measured. For the "goodness of sounds" factor, noise-added sounds were rated as lower than originals and down-sampled sounds, but for the "fineness of sounds" factor, no effect of processing of sound was observed. In EEG_s, by the addition of noise to the original sounds, power spectrum components of β waves increased, and power spectrum components of α waves and α/β ratios were reduced. Further, it was shown that α/β ratios in hearing the down-sampled sounds tended to be lower than in hearing the original music sounds. This result suggests that unperceived changes of sounds could be detected by monitoring the brain activities., application/pdf},
