When young, one of the authors heard someone say 'In fact there's little difference between the refreshing waterfall sound and the traffic noise on roads.' So-called good sounds include insects' chirping, tinkles of the wind-bell and piano tunes. Bad ones include noises of trams or machinery. What makes the difference between a 'good sound' and a 'bad sound'? This paper intended to visually compare the frequencies of various sounds using Windows Media Player. The results obtained were as follows. 1. So-called good sounds generally had sharp fluctuations in their frequency ranges as shown on attached graphs. 2. So-called bad sounds had less sharp fluctuations in their frequency ranges, hence did not show a clear sound. 3. However, the fluctuations of the waterfall sound and the fluctuations of the traffic noise of the road were not very different, which suggests for some sounds the existence of other factors such as listeners' psychology; memories of the past, the milieu and connotations.
