| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | It was reported that the existence of inaudible high-frequency components above 20kHz affects the acoustic perception of audible sounds (hypersonic effect) [1,2], and it is said that there are those who can perceive the differences between sounds with or without these ultrasound components among professional musicians or audio manias. There is the question of whether the existence of such “inaudible” high-frequency components may affect the acoustic perception of audible sounds for we ordinary people who had few opportunities to listen to the reproduction sound including the ultrasound components. In this report, it is experimentally discussed whether subjects (university students who had few opportunities to listen to such sounds) could perceive the differences between reproduction sounds, which were originally recorded in Super Audio CD (SACD) and divided into two frequency components at 8kHz, 12kHz, 16kHz or 20kHz, with and without high-frequency components. As a result, a tendency to support the existence of the effect is obtained and it is suggested that the frequency components of 16~20kHz are also important to the effect. | |
