Overall impression of long-term sound will be judged on the basis of memory and various factors may contribute to determining the overall impression. Among them cognitive and temporal factors may have a significant effect. The present study was designed to investigate the effect of these factors using a new approach. A stimulus consisted of various sound sources in our daily life. Subjects were asked to recall the sound sources and plot them on a loudness-time axis after judging the instantaneous impression corresponding to the instantaneous change of the stimulus. The subjects were asked to recall the sound sources again several weeks after listening to the sound. As the results it was found that subjects could recall the loudness and the temporal position of the sounds fairly well if they could recall the names of the sound sources. There was a tendency that the loudness and the temporal position seemed modified as the time passed as well as the decrease of recalled sound sources.
