“…In terms of 'Powerful', it is correlated with various types of acoustic parameters compared to 'Refined'. In the previous studies, 'Powerful' was one of the most mentioned variables in explaining the affective dimensions in the engine acceleration sound [4,49]. In this study, the acoustic parameters measured at the 2000 to 3500 RPM in the 3rd gear WOT sound showed a significant correlation with 'Powerful'.…”

The technical performance of recent automobiles is highly progressed and standardized across different manufacturers. This study seeks to derive a semantic space of engine acceleration sound quality for end users and identify the relation with sound characteristics. For this study, two affective attributes: ‘refined’ and ‘powerful’, and eight acoustic parameters considering revolutions per minute were used to determine the correlation coefficient for those affective attributes. In the experiment, a total of 35 automobiles were selected. Each of the 3rd gear wide open throttle sounds was recorded and evaluated by 42 adult subjects with normal hearing ability and driving license. Their subjective evaluations were analyzed using factor analysis, independent t-test, correlation analysis, and regression analysis. The prediction models for the affective dimensions show distinct differences for the revolutions per minute. From the experiment, it was confirmed that the customers’ affective response can be predicted through the acoustic parameters. In addition, it was found that the initial revolutions per minute in the accelerated condition had the greatest influence on the affective response. This study can be a useful guideline to design engine acceleration sounds that satisfy customers’ affective experience.

“…They found that respondents demonstrated a high degree of tolerance to the use of public loudspeakers in a residential environment if they were used for conveying necessary information. Fukuhara, Takanobu and Takamasa (2002) conducted experiments in vehicle acceleration performance and found the acceleration and accelerator pedal characteristic greatly influenced the evaluation of engine noise, across the two axis of "quiet feeling" and "sporty feeling." While these studies assert driving performance variables due in part to vehicle differences, they also highlight the affective responses to different environmental cues.…”

Two experiments are reported which explore the relationships between auditory feedback (engine noise), speed choice, driving violations and driver comfort. Participants played a driving simulation game with different levels of auditory feedback in the form of engine noise. In Experiment 1, a between-subjects design revealed that no noise and low levels of engine noise (65dBA) resulted in participants driving at faster speeds than in the medium (75dBA) and high (85dBA) levels of engine noise conditions. The low noise feedback conditions were also associated with decreases in driver comfort. Experiment 2 also demonstrated that low levels of engine noise feedback (no feedback and 70dBA) were associated with increases in driving speed, and driving violations relative to higher levels of feedback (75dBA and 80dBA). Implications exist for current car manufacturing trends which emphasise a growing increase in noise insulation for the driver.

“…Not only should these parameters be considered in the automotive industry, but also the acceleration performance feeling [13,14] should be included. For example, when an engine is accelerated the tail pipe noise should vary smoothly and linearly with the variation of engine revolution speed which will make drivers feel that the vehicle is accelerated and the sound is comfortable.…”
