Influence of visual information presentation method and sound presentation method on subjective evaluation of boat traffic noise

Information on the acoustic environment such as the engine noise of cruising boat on the canal is necessary for town planning. Miyagawa has investigated the influence of the visual of a sound source on an impression of the sound. The study has evaluated the shift on the impression of the sound by the visual stimulus. We focus on human subjective evaluation of the noise stimulus of moving source in this study. Our objective is to clarity the influence of visual information on the subjective evaluation of one moving boat noise. In this experiment, we examined the subjective evaluation of the moving source comparison between the stimulus of the sound and the stimulus of the sound and visual in the case of moving boat noise. This experiment used a 24-inch monitor, a headphone, or loudspeakers. The sound pressure level of 42–70 dB. As the result, the value of subjective evaluation was decreased by the moving source of loud boat noise, in the case of visual information of the moving boat.
