What is Active Sound Design?

Active Sound Design (ASD) is a technology that manipulates and enhances the sound produced by a vehicle's engine. Unlike traditional exhaust systems, which passively alter the sound based on their design, ASD uses electronic components to actively shape the auditory experience. This involves capturing the natural sound of the engine, processing it through a computer, and then playing it back through the car's speakers or a dedicated sound actuator. The goal is to create a more engaging and emotionally satisfying sound that complements the driving experience. In the Hyundai i30N, ASD is meticulously tuned to amplify the car's sporty character, providing a visceral connection between the driver and the machine. The system doesn't just make the car louder; it enhances the desirable frequencies, reduces unwanted noise, and synchronizes the sound with the engine's behavior. This results in a more refined and exhilarating auditory experience, whether you're cruising down the highway or tearing up a winding road. Moreover, ASD allows for customization. Drivers can often adjust the intensity of the sound enhancement, tailoring the experience to their preferences. In some cases, different driving modes may trigger different sound profiles, further enhancing the connection between the car and the driver's intentions. For instance, a comfort mode might offer a subtle enhancement, while a sport mode unleashes a more aggressive and pronounced engine note. This adaptability is a key advantage of ASD, making it a valuable tool for creating a versatile and engaging driving experience. The system must also be carefully calibrated to avoid sounding artificial or intrusive. A poorly designed ASD system can detract from the driving experience, creating a sound that is grating or unrealistic. However, when executed well, as in the Hyundai i30N, ASD can elevate the driving experience to a whole new level.
