Motorcycle riders enjoy the engine sounds like musical sounds during acceleration

抄録

For motorcycle riders, the sound is said to be an important key point to consider when choosing a model to buy. In the present study, a professional rider drove six sports-type model motorcycles on a chassis dynamometer with acceleration conditions. In the experiment, the impressions of the acceleration sounds were rated by motorcycle riders and non-riders, using semantic differential method. The results showed that the riders were more sensitive for the activity than non-riders. Moreover, the results of the experiment implied that the perceptual roughness was almost entirely determined by the architecture of the engine. Then, two psychophysical models of roughness and dissonance were tested for estimation of the impressions of the riders. The results showed that the dissonance matched to the impressions, rather than the psychophysical roughness. The riders may enjoy the acceleration sounds like musical tones rather than traffic noise.
