Preliminary Study on Implicit Driving Behavior Modulation via Engine Sound Modification

Year: 2025

Type: conference-paper

Abstract: This paper proposes a low-intrusion method for supporting safe driving by subtly altering engine sound feedback to influence drivers' perception of speed.Unlike conventional ADAS, our approach avoids explicit alerts and instead aims to induce unconscious behavioral changes.A driving simulator experiment showed that engine sound modulation-particularly to higher RPM-led to lower speeds, indicating that auditory feedback can serve as implicit driver behavior guidance.Questionnaire results revealed that the modified sounds often caused discomfort but were sometimes mistaken for actual speed changes.These findings highlight the potential of auditory feedback as a subtle and non-intrusive means of influencing driving behavior.
