ATTEMPT TO DETERMINE WHETHER HIGH-FREQUENCY SOUNDS AROUND THE AUDIBLE AREA WHEN THE STIMULI INTENSITY WAS VERY LOW AFFECT COGNITIVE PROCESSING IN HUMANS USING THE AUDITORY BRAINSTEM RESPONSE (ABR)

Abstract

In order to examine whether it is possible to activate the peripheral auditory system with high-frequency sounds around the audible area when the stimuli intensity was very low, an attempt was made to measure the auditory brainstem response (ABR). This study was intended to identify whether high-frequency low-stimulus sounds could influence cognitive processing in humans. The results showed that the potential could be evoked by a click and 4 kHz tone bursts. Additionally, a gender difference was confirmed in ABR. Finally, ABR waveforms were not observed when subjects were presented with high-frequency sounds around the audible range, suggesting that it would not affect the subsequent cognitive processes.
