What does an electric car sound like? How sound designers infuse electrified driving with emotion

Enter the world of sound design – a subtle factor that subconsciously shapes our entire sensory experience. In the automotive industry, sound design emerges as a pivotal player that influences functionality, safety, and customer experience. Engine sounds are more than just mechanical hums; they convey power and performance. Alerts are not only signals but also audio cues that enhance awareness. Even the subtle sound of tyres on the road contributes to an immersive journey.

When talking about cars, sound design is a storyteller that shapes narratives on the road, influences emotions, and elevates the overall drive experience. Sound becomes a soundtrack, transforming each drive into a captivating performance from point A to point B.

Electric car sound

As electric cars continue to become more popular, the absence of internal combustion engines has given rise to a challenge and opportunity: the necessity for sound design tailored specifically for electric cars. Recognising this, automakers have been investing in sound design to create electric car sound that not only adheres to safety regulations but also enriches the overall driving experience.

The sound produced by the engine of electric cars is directly correlated with the speed generated by their single-gear transmissions. In comparison to their petrol-fuelled counterparts, the engine noise of electric cars is characterised by a more uniform pitch.

This monotony in sound, however, is a drawback. As the overall noise levels of electric cars are much lower – considering the absence of engine noise, the primary sources of sound are the motor whine, wind, and road noise. Notably, accelerating in an electric car is quieter, lacking the audible cues that typically evoke emotions associated with driving fast. For certain drivers, the absence of sound-induced emotions contributes to a reduced sense of feedback and engagement in the driving experience.
