High-frequency components above 20 kHz can be recorded in recent high-resolution audio media. However, it is argued whether such the components can be perceived or not. In this paper, a psycho-acoustic measurement and auditory brainstem response in the high-frequency range are reported. In the psycho-acoustic measurement, some subjects could perceive the high-frequency sounds above 20 kHz and the auditory brainstem response could be measured for one subject at the frequency of 22 kHz. However, the sound pressure levels of the thresholds were beyond 80 dB in the both measurements. The results were unremarkable. Because auditory brainstem response is a direct signal from the auditory nerve, the nerve seems not to be stimulated by weak high-frequency sounds.
