Is the simulated engine sound inside or outside the car?
2 Answers
Simulated engine sound is inside the car. Here is an introduction to related content about simulated engine sound: 1. Volkswagen: Volkswagen installs a speaker near the engine throttle and further enhances the engine sound effect by using audio files in the vehicle's computer. Currently, this system is installed in high-performance models such as the Volkswagen Golf GTI, Jetta GLI, and Golf R, producing amplified sounds. 2. BMW: The BMW M5 adopts a similar sound packaging method to provide drivers with better auditory effects. The system is called Active Sound Design. Its working principle involves pre-recording the engine sound, and then the vehicle's computer automatically adjusts the audio effect based on the actual engine speed during driving. Therefore, it's not without reason that many people refer to BMW as the master of sound effects.
When I learned about cars, I noticed that simulated engine sounds are generally played inside the vehicle. Specifically, they are achieved through the car's audio system. For example, in electric vehicles, speakers installed in the cockpit simulate engine sounds to make the driver feel more like they're driving a traditional fuel-powered car, providing RPM feedback or enhancing the driving experience. It is not designed to propagate outside the vehicle, as that could cause noise pollution or disturb pedestrians. However, pedestrian safety needs in the external environment are sometimes considered by manufacturers, so dedicated external speakers are added at low speeds to alert passersby. This technology stems from the natural quietness of electric vehicles. Manufacturers use digital processing to customize different sound modes, ranging from engine roars to turbocharged sensations, enhancing driving immersion without increasing actual emissions.
