Abstract
In the development of a new model of cruiser-type motorcycle, the quality of its exhaust sound was tuned up by using the exhaust sound in the opening and closing action of the accelerator. Using samples of exhaust sound taken from such a condition, a sensory evaluation test was conducted by a semantic differential method (SD method).
As a result of factor analysis, two factors, deepness factor and distinctness factor, were selected as representative factors for evaluation of the exhaust sound quality of cruisers. By mapping sound samples of these factors, the position of the target exhaust sound for the model under development was identified. The effects of the physical properties of sound on the deepness factor and the distinctness factor were clarified. The mufflers were then adjusted to achieve the target sound quality. This paper reports on this experiment.
