Audi Gives Silent Electric Car Synthetic Sound
itwbennett writes "Audi's electric cars are quiet, maybe too quiet, which is why Audi spent 3 years creating replicated engine noise for its electric car models. We're so conditioned to the noise of an engine revving that a driver behind the wheel of a too-quiet car may not realize how fast he's driving, and a pedestrian relying on auditory clues may be unaware of an approaching vehicle, says Ralf Kunkel, Head of Audi Acoustics." Nissan's been on this for years (as has Honda); one day, you may only get to choose which noise your car makes, rather than whether it does.
NHTSA FARS data, 2002-2006: 27 legally blind pedestrians were killed by automobiles. 27/5 == 5.4 per year. Blind people being run over by automobiles simply isn't a rampant problem. Blind people often rely on audio cues to cross the street, but not the sound of engines. Instead, the chirp or verbal commands from crosswalk signal heads is the audio cue for blind pedestrians, combined with the trust that motorists will look for peds when turning right at intersections.
It's noise pollution, and it's oh so unnecessary.
Support a few technologists in Washington.
The nonsense about electric cars is no different. It's just attempts by the lobbying department of interested automobile makers (the ones who aren't adapting to the 21st century) using bribed republicans and regulatory capture to try to create artificial barriers to adoption against their competition.
A very long time ago steam was the proven technology, electric cars were considered quiet and civilized, and gas engine cars were the noisy, dangerous, smelly upstarts. The gas engine car manufacturers engaged in a major FUD campaign against electric cars. They were dangerous! They were so quiet you couldn't hear them coming...
We have an active electric vehicle club here in Vancouver. The loudest noise their best conversions make is the whirr of the tires, sometimes with a slight groan from their power controllers. They have a 1912 Detroit electric car, and it's almost completely silent.
Our bus system has one of the larger fleets of electric trolley buses in the western world. They too are very quiet, but people get used to looking for them before crossing the street.
