掃除機放射音を対象とした受聴状態の違いが音質評価に与える影響

抄録

In this study, annoyance of vacuum cleaners were evaluated when the participants operated the machine (active condition) or they sat on a chair (passive condition) to investigate the influence of the mental state on the sound quality evaluation. As the result, averaged annoyance score of the passive test was significantly larger than that of the active test. In addition, the difference of the annoyance score between passive and active conditions in A-weighted SPL was estimated by using the relationship between the subjective annoyance score and the SPL of the evaluated sound. The result indicated that the SPL of vacuum cleaner in the passive condition was necessary to be decreased about 5 dB to equalize the annoyance in the active condition.
