The authors have developed a new system for sound presentation and a novel technique to measure brain electric activity, and used them to determine if high frequency components above the audible range can influence sound perception in ways not discerned by the method of paired comparisons. The authors report that high frequency sound induces activation of electroencephalogram rhythms that persist in the absence of high frequency stimulation, and can affect perception of sound quality.
