Abstract

Little is known about the role of low-frequency components in sound. The case of a 40 Hz sine wave mixed with music or sounds were investigated. We confirmed that autocorrelation structures arise when the amplitude of mixed 40 Hz sine waves is large. The frequency spectrum analysis shows the presence of superposition of the 40 Hz sine wave and the music/sound wave. When the high-frequency component of the music is small and the amplitude of the mixed 40 Hz sine wave is relatively large, the superposition of the waves strengthens the high-frequency component. And also, mixing the 40 Hz sine wave with White noise, Brown noise, and Gray noise enhances different frequency components. The low-frequency mix has the effect of strengthening the low-power frequency components.
