Whether inside the cabin or outside the vehicle, a rich engine sound is an integral part of the experience behind the wheel and plays a crucial role in defining the DNA of a car.

This holds especially true when engine sound gets attenuated as OEMs engage in measures such as engine downsizing and the use of turbochargers in order to reduce emissions and fuel consumption.

Moreover, due to the silent nature of their powertrain, electric and hybrid vehicles lack (sonic) feedback on speed and rate of acceleration that drivers are generally used to. Pedestrians, bicyclists and other road users who are accustomed to relying on auditory cues from vehicles to navigate around traffic fail to hear approaching electric/hybrid vehicles. The SPb Audio Lab Electronic Active Sound Design solutions – internal Digital Sound Synthesis (iDSS) and external Digital Sound Synthesis (eDSS) – help to solve these issues, enabling OEMs to attain the targeted engine sounds reflecting the sound DNA of their cars.
