For Electric Cars, Silence Is No Longer Golden

For more news visit ☛ english.ntdtv.com Researchers in England say legislation to force silent electric vehicles — or EVs – to make a warning noise is now inevitable. The scientists are looking for a sound that is both effective and pleasing to the ear. Their prediction is based on news from the US showing that twice as many pedestrians and cyclists are hit by hybrid EVs than by conventional vehicles. This is “ELVIN” – a silent, electrically-powered truck that is making a noise for itself. It was designed at the University of Warwick in England where researchers are trying to decide what noise silent vehicles should make – if they are forced to by law. Something Professor Paul Jennings says is inevitable. [Professor Paul Jennings, Warwick Manufacturing Group] “It’s definitely coming and I think it’s being prompted by the fact that there are now real statistics that sadly are possibly showing an increase in accident rates for certainly hybrid electric vehicles at the moment. And I think it’s only at low speed where the quietness is most evident.” The Warwick Manufacturing Group has spent years working in the industry to make cars quieter – now they are in reverse gear. [Professor Paul Jennings, Warwick Manufacturing Group]: “What we want to do is try to investigate sounds that are going to be safe, have minimal effect on the environment and are going to give some creativity to the manufacturers.” The team wants to know what kind of noise is most effective, and have …
Innovative technology often can make yesterday’s science fiction into today’s reality. This is particularly true with a prosthetic hand that brings to life fictional accounts of artificial, computer-driven replacement body parts. The bionic hand, called the I-Limb,was named one of the top 50 inventions this year by Time Magazine.
