Hybrid Cars: make some NOISE!
Quiet cars, namely Hybrids and Electrics, are under the spotlight after the US National Federation of the Blind voiced its concern about the noise they generate, or rather their lack of noise. In a world that invented double glazing and earmuffs to combat traffic noise, among other things, it would seem that there’s a positive to a loud engine – it lets pedestrians know there’s a car coming and, of course, this is helpful for people with impaired vision.
The Federation suggests that a minimum noise level should be set for all vehicles, and in an urban environment it makes sense – however, try telling that to folk who live within earshot of a motorway. But how do you make a quiet car noisy? Making them sound like wasps is one suggestion...
