To address complaints about irritating sounds on train station platforms beyond the limitation of conventional noise reduction approaches, we applied the hypersonic effect, which refers to the positive way in which inaudible complex high frequency components (HFCs) produces a salutary physiological and psychological effect on human through the activation of fundamental brain. We created a virtual platform acoustic environment in the experimental room as well as actual platform space by reproducing highly accurate broadband recordings of actual platform sounds. We developed hypersonic contents of effective HFCs obtained from a rainforest environment and developed hypersonic public announcements and hypersonic departure bells containing HFCs. We evaluated the psychological and physiological effects of hypersonic contents presented alongside the platform acoustic environment. Subjects showed significantly more positive impression of the acoustic environment and significantly greater alpha 2-electroenchephalography potential, indicating the efficacy of the hypersonic effect in ameliorating the unpleasantness of a noisy environment.
