Cars and SUVs next to having loud engines are also spewing carbons emissions. Any Quiet electric car when compared to a loud SUV with a rumbling V-6 and emitting foul smoke is heaven. Killing two birds with one with relative ease is an EV.

Cars and SUVs next to having loud engines are also spewing carbons emissions. Any Quiet electric car when compared to a loud SUV with a rumbling V-6 and emitting foul smoke is heaven. Killing two birds with one with relative ease is an EV. Also, SUVs are unsafe for pedestrian as wells.

 Something is not right and if guessed right, then good. Despite all the negatives of a loud and pollutive car. They can be seen, smelt and heard when approaching on the road. Alarming pedestrians to be aware and take safety measures.

Problems of electric cars that have soft sounds are explained. Easier to avoid a huge lumbering SUV or any speeding maniac in a car. All because they have noise to a warn anyone, short of deafness. What makes street safe are the stoplights and traffic rules, but most importantly noise from cars in the environment.

 Blind individuals are the most affected by silent electric cars. Not hearing the sound of an approaching electric car is very dangerous for them. Requiring sound from EV car makers is mandatory for many countries with EVs operating. This was unforeseen but a necessary step to make roads safer for the blind, pedestrians and cyclists who share the road with cars.

 The EU requires sound-equipped EV cars that even work below 12 mph. All vehicles should have it by the year 2021. Unlike, the US where engine sounds should be heard at 18.6 mph short of 19 mph. Cars are mobile, so they are the safety threat to worry about. Sounds are required by law in the US when they reach speeds of 18.6 mph by 2020. Studies show that certain ranges, both electric motors and tire rubber make noise.

 Mercedes-Benz installed audio alert systems for cars bound to the US, Japan, Europe and China dealerships worldwide. Car sound for Japan and the EU are the same, for US cars it is different,

 Sound engineers at Daimler preferred a sound that is not annoying and like a gas engine. No weird sounds but acoustics that is natural.  

 Mercedes EQC EVs compared to regular cars sound like an internal combustion engine (ICE). Engineered auto noise for US version sounds like a rumbling machine. Both when backing up produce beeping sound like a truck. Chevy Bolt got engineered sounds as dictated by the NHTSA (National Highway Traffic Safety Administration) which did not interfere with vehicle noise and was not obnoxious.

 Jaguar has a compliant audio alert system for the I-Pace Lux crossover. Compatible with either EU and American standards. Designed to have spacecraft sounds that distract pedestrians on the road. Instead, a hybrid sound that combines mechanical tones and electric motors whirring. 

 New developments with the Bolt is placing a speaker on the car centerline nose and the rear for backing up. Another suggestion is more than one sound, not just a default. It seems electric cars cannot be quiet and creating sound is for safety measures to safeguard pedestrians. All these EVs should have noise or be a menace.
