• In order to evaluate community noise, the measurement of long-term noisiness is very important. However the conventional psychophysical method is inappropriate for this purpose. Using the newly developed "method of continuous judgment by category, " the relationship between instantaneous judgment and long-term noisiness was examined. Aircraft noises overlapping background noises were adopted as stimuli. As a result, it was suggested that long-term noisiness was determined by the prominent pars of instantaneous judgment. And it was made clear that the aircraft noise to background noise ratio had much effect on the overall noisiness of aircraft noises.
