  • Psychophysiological Effects of Levels and Spectral Properties of Noise Added to Original Music Pieces, TAKAYAMA Tomoyuki, Research reports of the Faculty of Engineering, Kindai University, Research reports of the Faculty of Engineering, Kindai University, (52), 47 - 56, Dec. 2018
    Summary: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.
  • Influences of acoustical processing on impression evaluation of music pieces, and its physiological correlates, TAKAYAMA Tomoyuki, Research reports of the Faculty of Engineering, Kindai University, Research reports of the Faculty of Engineering, Kindai University, (52), 39 - 46, Dec. 2018
    Summary:Present study investigated relationships between impression evaluation and acoustic variables, and their relationship with physiological indicators, after extracting the impression evaluation dimensions of classical music pieces and sorting out the impression evaluation items, similarly to the previous report (Takayama, 2014). Using a total of 12 evaluation sounds consisting of four original sounds, their downsampling ones, and their noise-added ones, experiments on impression evaluation and electroencephalogram measurement on listening at evaluation sounds were conducted. As a result, we found that the difference of music pieces and the acoustic processing affected all the impression of "goodness of hearing", "lively motion" and "profoundness", respectively. On the other hand, the EEG indexes were not varied by the difference of music pieces or the acoustic processing. Regardless of the difference of music pieces and the type of acoustic processing, the correlation between the impression evaluation values of music pieces and the EEG indexes indicated that, as the impression of "lively motion" or "profoundness" strengthened, the α wave content rates and the values of α / β ratio decreased, while the β wave content rate increased.

  • A phonemic perception as a matching to phonemic representation in long-term memory, TAKAYAMA Tomoyuki, Research Reports of the School of Engineering, Kinki University, Research Reports of the School of Engineering, Kinki University, (39), 75 - 83, Dec. 2005
    Summary:Previous studies (Takayama,2002,2003) indicated that,in the identification learning of sinewave analogs of stop CVs or vowels,performance under speech instructions using phonemic labels matched to analogs was superior to performance under nonspeech instructions using arbitrary labels,which was better than performance under speech instructions using mismatched phonemic labels. Present study aimed to replicate these findings using analogs of other speech sounds,Japanese "わ"and "ら" in the first experiment and American English /la/ and /ra/ in the second experiment. It was predicted that the superiority of matched speech instructions over other instructions (and nonspeech instructions over mismatched speech instructions) should be found in learning on analogs of native syllables,but that,in learning on analogs of nonnative syllables, no difference should be among instructions groups. These predictions were mostly confirmed. The hypothesis that a phonemic perception is a process in which perceptual representation of signals is matched to phonemic representation in long-term memory was discussed.
  • Priming effects in speech and nonspeech modes of perception, Tomoyuki Takayama, Acoustical Science and Technology, Acoustical Science and Technology, 25(3), 196 - 202, May 2004 , Refereed
    Summary:A phonemic perception was assumed to be a process in which representation of speech signals is matched to phonemic representation in long-term memory. Since stimulation is supposed to activate relevant memory representation, priming effects were compared between speech sounds and their sinewave analogs, either in the speech mode or nonspeech mode of perception. An analog target imitating syllables /ba/ or /ga/ in Session 1 or their original speech target in Session 2 was preceded by one of 5 primers, which were these 4 target sounds, and a 1,000 Hz pure tone, with one of 6 interstimulus intervals (ISIs). In Session 1, half of the participants were asked to identify analogs as ill-synthesized syllables, "BA" or "GA," and the other half were asked to label them as computer sounds, named "A" or "B." In Session 2, all of them identified original syllables. Regardless of target types and ISIs, subjects given speech instructions showed faster identification of targets preceded by phonemically identical primers, while subjects given nonspeech instructions identified targets faster only when targets were preceded by physically identical primers. These results support that speech sounds and their analogs are accessible to common memory representation.
