Noise with a prominent pure tone component, such as motor and gear noise, is perceived by the auditory sense to fluctuate in frequency and amplitude with changes in rotation speed. In this study, the frequency sweep width and frequency sweep speed are considered as the frequency change of the pure tone component, and the amplitude change width and amplitude change speed are considered as the amplitude change of the pure tone component. The cases in which frequency modulation and amplitude modulation occur as modulation of the pure tone component are also considered. The sound quality of these non-stationary sounds will be evaluated to estimate the parameters that are sensitive to human hearing.
