2012 Audi R8 e-tron – Acoustic Innovation e-sound – Traffic Situation

Acoustic innovation: e-sound by Audi • The brand is developing new sound signatures for its future e-tron models • A control unit generates sound based on signals from the car • A loudspeaker broadcasts the sound signature Audi’s future e-tron models will cover long distances powered by practically silent electric motors. To ensure that pedestrians in urban settings will hear them, the brand has developed a synthetic solution: Audi e-sound. Rudolf Halbmeir’s workstation is not exactly typical of an Audi engineer. There is a digital piano on his desk, two studio-quality loudspeakers next to his computer monitor, and a pile of music magazines off to the side. “A car’s sound,” says Halbmeir, an acoustics engineer, “is similar to music.” Sound is an especially exciting aspect of a vehicle. Although it can be described in physical terms, there is no substitute for experiencing it firsthand. A car’s sound is emotional, not intellectual.

It would be a cheaper solution and makes much more sense! If that isn’t enough, stick a flashing light on their heads!
