Abstract (in Japanese) (See Japanese page) 
(in English) The production concept of car engine sounds has evolved from one of noise reduction to one of sound design. Auditory impressions have been examined from a psychological point of view. However, it is difficult to gain a full understanding of the issue using this approach alone. Thus, we investigated the relationships between subjective preference and brain magnetic fields for accelerating car interior noise.
First, harmonic complex tones that simulate acceleration noise were used as stimuli. Subjective evaluations were examined using the semantic differential (SD) method and neuronal activities of the auditory cortex evoked by these stimuli were measured by magnetoencephalography (MEG). The results indicated that has a significant effect on subjective impressions and on neuronal activities of the auditory cortex.
Second, the acceleration noise was measured with an in-line 4-cylinder engine and harmonic complex tones that simulate acceleration noise used as the stimuli. Subjective evaluations were examined using the paired-comparison method. At the same time, the MEG alpha-waves range (8-13 Hz) measurements were made and analyzed using the ACF (autocorrelation function). The results indicate that the effective duration of the ACF of the MEGs of between 8 and 13 Hz lengthens after the presentation of a preferred sound.
