e-ASD (electric vehicle Active Sound Design) is an electric vehicle-only technology that outputs a virtual sound suitable for vehicle characteristics while driving. It provides optimized sound and volume by reflecting the number of revolutions of the electric motor and the overall driving load of the vehicle in real-time. In addition, the volume can be adjusted in several stages according to the owner's taste. It supports the 'Accelerator Pedal Sound Response' function that directly sets the degree to which the volume and tone change according to the degree to which the accelerator pedal is operated. For reference, Hyundai Motor Group provides various concepts of sounds by analyzing preferred sounds by continent and region. For example, for Genesis GV60, there are three sound styles: the 'Futuristic' sound that gives a futuristic feel, the 'G-Engine' sound that gives the sporty feel of an internal combustion engine, and the 'E-Motor' sound that emphasizes the noise of the motor. They deliver different kinds of pleasure to the driver.
