Audi develops artificial sound for EVs

Audi’s future e-tron electric vehicles will be powered by practically silent electric motors, so to ensure pedestrian safety in urban settings, Audi has developed the Audi e-sound, which will allow pedestrians to still hear the vehicles.

Similar to the technologies developed by the likes of Fisker and Lotus, the e-sound is an artificial sound, played via a sturdy loudspeaker attached to the car’s undercarriage. In a series-production Audi, a combustion engine currently supplies the soundtrack. However, Audi says that because the motor in an electric-powered e-tron is too quiet and its high frequencies not melodious, e-tron models will feature a synthetic sound signature. Using computer software to mix, listen to tones, assess and then re-mix, the e-sound has been created.
Dr Lars Hinrichsen, expert for hardware and software working on the project at Audi, explained, “Data relating to the electric motor’s rotational speed, vehicle speed, loads, and other parameters is continuously supplied by the vehicle to the control unit. It then uses this data to generate sound.”
Axel Brombach, specialist in the field, added, “We designed it to handle as much as 40 watts, but during normal operation it ranges between five and eight watts. That’s loud enough for nearby pedestrians and cyclists to hear the e-tron.”
