Abstract
In recent years, the healing music of low and middle frequency sound is very popular among every generation. While, it is told that the highest quality sound such as Stradivarius violin includes smooth harmonic sound over 20kHz which is not audible but is one of the reason for the beautiful sound. Therefore, the healing effect of high note sound such as trumpet and cymbal are newly tested by the electroencephalogram (hereafter EEG) of a simplified brain waves device when audiences are listening to a Super Audio CD (hereafter SACD) and an actual musical instrument. As a result, the high note and high quality sound not only generates alpha wave but beta wave, which means that the high quality sound is affected to the brain waves and is well balanced with hearing and exciting effects. In the near future, this analysis method using EEG and sensory evaluation will be reflected to the further improvement of cymbal sound quality.
