ABSTRACT:
Background and aims: The music tempo and sound pressure levels significantly impact driving performance, considering individuals' personality traits. The studies indicate that more than environmental factors, personality characteristics also affect driving performance. This study explores the influence of music tempo and sound pressure levels on driving performance indicators.
Methods: This research was cross-sectional performed with 90 participants aged 20-35 in 2023. The participants underwent driving performance assessments using a simulator. Performance indicators including driving speed, braking reaction time, and lateral car deviation, were measured. Participants completed demographic and Eysenck's personality questionnaires and then drove the simulator for 15 minutes under various musical conditions. Data were collected using MATLAB software and analyzed using SPSS24.
Result: The participants’ mean age was 24.0 years with a standard deviation of 3.77, 38 were women and 52 were men. The average driving speed across five groups was close to the significant level (P=0.054). The participants with low tempo and high sound pressure had the most speed. There were 33 and 49 introverts, and extroverts participants in the study. Additionally, introverts had longer braking reaction time compared to extroverts. The correlation between braking reaction time, and number of collisions was 0.086 and non-significant. Furthermore, the correlation between speed and number of collisions was 0.23 and significant (P=0.027).
Conclusion: The results show that with the consistency of sound pressure, the low tempo had negative impact on diving performance, and this is due to decrease of excitement. It seems the music has more impact on driving performance of introverts than extroverts.
