Noise samples of motorcycles at different engine speeds taken at the position of the ear of a motorcycle operator are selected as the evaluation stimuli to investigate sound preferences of motorcycle sound quality. Subjective testing is carried out via the paired comparison method. Precise calculation of the misjudging rate is adopted to ensure test result reliability. Formulae between subjective preference scores and psychoacoustic parameters are obtained through linear correlation and multidimensional regression analysis. The results indicate that loudness and roughness are two predominant metrics influencing preference evaluation for motorcycle noise, and the nonlinear equation better describes the dependence of subjective preference scores on psychoacoustic parameters than the linear one.
