Is the simulated engine sound inside or outside the car?

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.

When driving a new energy vehicle, I experienced that the simulated engine sound is mainly played through the in-car speakers. It allows me to hear the changes in engine noise, as if I were controlling a performance car, while people outside the vehicle hardly notice it. This is because electric vehicles are inherently quiet, and the built-in sound provides drivers with a familiar sensation, aiding in judging acceleration timing. However, simple sound effects may be added in low-speed zones outside the vehicle to warn pedestrians, but the core function remains internal—ensuring safety while avoiding noise pollution. It's very convenient for adjusting the driving atmosphere during daily commutes.

As an environmentally conscious individual, I've noticed that simulated engine sounds are often deployed inside the vehicle. They utilize the audio system to mimic engine noise, specifically designed for the driver to enhance the driving experience without increasing external pollution; while exterior sound considerations focus on safety factors such as pedestrian alerts.

I enjoy the simulated engine sound in my car, which is entirely played inside the cabin. The manufacturer uses the audio system to recreate the sound of a real engine, making me feel more dynamic; it has minimal impact outside the car, except for low-speed safety design.

From a safety perspective, simulated engine sounds are primarily implemented inside the vehicle. The onboard speaker system creates engine feedback to help drivers maintain acceleration rhythm; meanwhile, the low-speed external sound component is used to alert pedestrians and prevent accidents, striking a balance between driving pleasure and public safety.
