The noise-free nature of electric vehicles may be an advantage for most people, but at the same time, when the vehicle glides on the road in a near-perfect silent state, it also poses a potential hazard to passers-by. To this end, the car manufacturer Audi is trying to find an ideal "sound" for electric vehicles.

This sounds a bit contradictory: one of the most eye-catching features of electric vehicles, no noise - neither the rumble of the six-cylinder sports car exhaust pipe nor the answer of the diesel engine - but the potential for pedestrians Danger. It is understood that when an electric car is driven at a speed of 25 kilometers per hour, basically no noise is generated. Only when driving at a higher speed, the noise from the tires is started to be heard; while on the highway, the electric vehicle is used. The noise generated will be similar to that of a conventional car.
But for traffic safety experts, the noiselessness of electric vehicles is a headache; they worry that because passers-by have long been accustomed to the "sound alarms" produced by traditional cars, they may not be able to detect the electrics that are staggered. The car caused some imaginable accidents. To this end, the Association of Visually Impaired People around the world has requested that electric vehicles be equipped with special sounds to warn the visually impaired compatriots that relevant legislative actions have taken place in Japan and the United States.
Like other automakers, Audi recognizes the above risks and has embarked on a research and development project to find the most appropriate sound for the company's future electric vehicles. “As long as the electric car is driving at a speed range of 0 to 25 km/h, it is the “silent car†we discussed;†Ralf Kunkel, who is responsible for the Audi electric car sound development program, said that their team of engineers is planning to be on the future electric car. Equipped with some kind of electronic sounder, but the question is what sound should the electric car be?
For Audi's engineering team, letting the electric car make a sound is not only a warning for the approach of the vehicle, but also a task to develop the exclusive electric car sound of the car manufacturer to establish a "sound brand recognition". “Of course, it’s natural to develop the sound of an electric car based on the sound of the internal combustion engine that we are familiar with;†Christian Schueler, head of Audi’s brand development and corporate identity business, said: “On the other hand, we intend to emphasize electric vehicles or hybrids. The innovation of vehicle products, and hope that our brand can also be 'listen' in the era of electric vehicles."
Audi's engineering team is currently considering which sound to choose for an electric car; the company revealed that some of the sounds of spacecraft like sci-fi movies have been eliminated, and no other specific plans have yet been formed. The goal of the engineers is to make the Audi electric car sound "very innovative".... Perhaps it would be a good idea to use the sound of the Audi RSQ, the concept sports car that appeared in the movie "I, Robot".
USB C Cable
A USB-C cable is a recent type of USB connector that's easier to use and more powerful than older USB types. USB-C cables can be used to quickly charge many popular devices, including the MacBook Pro and Nintendo Switch, and transfer data faster than any other USB type.
