Abstract

Since the advent of steam-based automobiles for the first time in the 18th century, automotive technology has improved dramatically over the past 100 years. Recently, the 5GA (5G Automotive Association) was launched in time for the 5G era. For the 5Gs, eco-friendly automobiles were named. Currently, most of the automobile market uses internal combustion engines. Internal combustion engine cars have the disadvantage of causing environmental pollution and air pollution. Environmentally-friendly automobiles have been developed to be capable of high-speed driving, and are superior in noise, fuel efficiency and environmental factors compared to vehicles using internal combustion engines. However, there is a disadvantage in that a virtual engine sound is not as full as the richness of an internal combustion engine’s sound during acceleration. Therefore, in this paper, we study the virtual engine sounds that can enhance the feeling of acceleration by controlling the playback speed of a virtual engine sound. Experimental results showed that an engine sound with 4 s playback time adjusted from the engine sound of 1–5 s can enhance the feeling of acceleration the most. An MOS test showed that the virtual engine sound was not much different from the engine sound of an existing engine.
