Recently, many automakers have started to make their electric cars louder by adding artificial sounds. Well, what's the reason for this? Why are vehicles getting louder and louder? Let's examine the answers to these questions together.
Auto companies always use sound to enhance a car's personality and increase the perception of performance. A sufficient acoustic signature announces the vehicle long before it arrives; enthusiasts can predict a car's brand, model, and even the year it was produced, based on the distant noise of the engine.
At this point, electric vehicles that take their power from the battery instead of the internal combustion engine do not make much noise at low speeds. Silence poses a significant danger to cyclists and pedestrians who cannot hear a car sneaking behind them, as well as for visually impaired people who rely on sounds to detect approaching vehicles.
Different sounds for different actions:
Both gasoline and electric vehicles generate wind and tire noise at speeds above 30 kilometres per hour. But below this threshold, it can be said that electric cars are almost entirely silent. Therefore, according to new regulations in the USA, vehicles must emit sounds at different frequencies while travelling at speeds up to this limit.
At this point, the sounds it produces while accelerating, slowing down and reversing should be different from each other and should make a sound of at least 40 decibels while stopping. That's why most manufacturers focus on different sounds to give their electric vehicles a futuristic feel.
Currently, many of the world's leading different auto giants are working on different sounds to strengthen the personality of their vehicles. At this point, we can say that there is a high probability that we will see cars making bizarre noises in the future.
Artificial sounds are added to electric vehicles:
This is precisely the reason for the federal law, which entered into force in the US last September, requiring electric vehicles to make an artificial noise when cruising and stopping at low speeds. The noise should be loud enough to alert pedestrians and indicate if the car is accelerating or decelerating. This gives car manufacturers a chance to create a sound that will add their personality to their electric vehicles.
Many companies are already coming up with unusual ideas. Lincoln, for example, hired musicians from the Detroit Symphony Orchestra to create blended warning sounds from percussion and string instruments on their latest SUVs. German giant BMW, on the other hand, agreed with Hans Zimmer, who is competent in his job, to voice the Vision M NEXT concept electric car.
