We evaluated the effects of the intensity of inaudible high frequency components (HFC) of sounds on human by employing a multiparametric approach, consisting of a behavioral experiment using comfortable listening level (CLL), psychological experiment using Scheffe's paired comparison method and physiological experiment using electroencephalogram. The enhancement of HFC significantly increased the CLL and made the sounds more natural and richer in reality and information, which suggests that the sounds with enhanced HFC increase positive impression and comfort of the sound. The sounds with enhanced HFC also showed a trend to increase the power of the alpha frequency range of electroencephalogram.
