Loud Sound Requirement For Silent Automobiles

By Cornelius Nunev


Though it is not the main feature of electric automobiles, their quiet operation has often been cited as a fantastic side benefit. Electric and hybrid cars are the target of some new legislation. The legislation would require these quiet automobiles to make more noise. There is already after-market technology accessible to add the roar of a motor to hybrid automobiles.

The troubles with silent vehicles

Hybrids and electric automobiles tend to be fairly quiet when going slow. Generally, the cars will make sound over 20 miles per hour from the air resistance, although it isn't at all the same as a gas auto would make. Noise pollution could possibly be helped greatly with these vehicles. It is still a problem for anyone who needs the sound though. Pedestrians, cyclists and sight-impaired individuals often cannot identify which direction a hybrid or electric automobile is coming from until they are very close. A hybrid or electric automobile is two times more likely to hit a pedestrian. This is mostly only when it is going at very slow speeds.

How car makers act

Most car manufacturers are already working on the car sound issue. This involves businesses such as Nissan. A "futuristic buzzing noise" will be found in later models of the Nissan Motors Leaf. Separate companies, for instance Lotus Engineering, are creating kits that add realistic engine rumbling to hybrid vehicles. One kit makes a Prius sound like a race car. Whenever people decide to add sound to their hybrids, some have the possibility of making it sound like an 8- or 12-cylinder car.

Creating a better country

According to the National Highway Traffic Safety Administration, sound is very important. It may even put a noise requirement on automobiles. The European Union is also considering similar regulation. Automakers have been asking if it is possible to do natural noises. Most blind-advocacy groups are against this though. The Society of Automotive Engineers is working to create what it hopes will be worldwide standards for electric and hybrid noise to ease the transition and prevent a virtual cacophony of different electronic sound on highways and freeways.
