This paper describes an experimental investigation result as to how the audio signal (i.e., sound and music) gives feeling impression to us and how the impression changes, depending on the distribution of power spectrum in Fourier domain of the audio input signal. In this investigation, we use three kinds of parameters accompanying the calculation of the signals' fluctuation degree. Then we examine the relationship between the parameters and affective impression, by using questionnaire survey. And also, from the viewpoint of feeling impression, we classify the sound signal by the values of three kinds of parameters. In this paper, we present the experimental results and show that the fluctuation degree and residuals are highly related to good impression
