N2 - Subjective impression of steady-state and intermittent sounds was examined. The component sound of intermittent sounds has 30ms rise- and fall-time without steady-state portion and LAmax was 70 dB. The carrier was white noise. The number of component sounds was varied from 5 to 80 in 4800ms total duration of the sound. The steady-state sound with the same duration was also used. The sound levels of the steady-state sounds were 53, 59 and 65 dBA. The loudness and the subjective impression of these sounds were judged using magnitude estimation and semantic differential, respectively, by fourteen German participants. The results showed that the loudness of intermittent sounds was judged louder than that of steady-state sound even if LAeq and L AE values were equal. It was also found that the intermittent sounds were judged more annoying and unpleasant than steady-state sounds. These results suggest that affective impression has an effect even on the judgment of loudness.
